A hexagonal pyramid has one curved surface, which is the lateral surface that connects the apex to the base. The base of the pyramid is a hexagon, contributing six flat surfaces. Therefore, in total, the hexagonal pyramid has one curved surface and six flat surfaces.

Four thirds of pi x the cube of the radius

Vol(cube) = length(diameter)^(3)

Volume(sphere) = (4/3) pi* radius^(3)

Now the radius is '1/2 ' the diameter/length , assuming as 'perfect' fit.

So substituting

Vol(cube) = (2radii)^(3) = (2r)^(3)

To find the 'Ullage' unused space, subtract one from the other.

Vol(cube) - Vol(sph).

(2r)^(3) - (4/3 pi*r^(3)

Factor

r^(3) [ 2^(3) - (4/3 pi ]

=>

4r^(3) [ 2 - pi/3]

NB ' pi = 3.141592.....

So all you need is to find the length of one side of the cube and halve it.

So if the cube is 64 units^(3)

Then the side length is the cube root of 64 units^(3) , which is 4units.

Half of this side length is 2 units ( 4/2) , this is the radius(r).

Substituting

Ullage space is 4(2)^(3) [ 2 - 3.14 / 3] ==>

4(8)[ 2 - 1.047...]

32[ 2 - 1.047...]

32[ 0.9529...] == >

30.9438.... units^(3) is the volume of the Ullage space.

Length = 4 units

Area ( of a face) = 4units x 4 units = 16 square units

Volume = 4 units x 4 units x 4 units = 64 cubic units.,

The volume of a cube is a side cubed.

V=S3

So, to find the length of a side, solve for S, to find that the side equals the cube root of the volume.

Ex: Volume=8 cubic meters

Then 8=S3, therefore s=2 meters.

Well, isn't that just a fun little math problem! To find the side length of a cube with a volume of 1331 m³, you simply need to take the cube root of 1331. So, the side length of this cube would be 11 meters. Voilà!

The measure of an interior angle of an 18-gon can be calculated using the formula ((n-2) \times 180^\circ / n), where (n) is the number of sides. For an 18-gon, the interior angle is ((18-2) \times 180^\circ / 18 = 160^\circ). The measure of an exterior angle is (180^\circ - \text{interior angle}), which gives (180^\circ - 160^\circ = 20^\circ). Thus, the interior angle is 160° and the exterior angle is 20°.

A reflection across the x-axis is a transformation that flips a point or shape over the x-axis. For a point with coordinates (x, y), its reflection will be (x, -y), meaning the y-coordinate changes sign while the x-coordinate remains the same. This transformation creates a mirror image of the original point or shape below the x-axis. It is commonly used in geometry and can be applied to entire figures as well.

A shape that is symmetric about its centroid will always have its centroid located within the lamina. This includes regular polygons, circles, and any shape that is uniformly distributed around a central point. In general, convex shapes also have their centroids located within their boundaries. Conversely, concave shapes may have centroids that lie outside the lamina.

To find a co-terminal angle for -32 degrees within the range of 0 to 360 degrees, you can add 360 degrees to -32. Doing so gives you -32 + 360 = 328 degrees. Therefore, the co-terminal angle of -32 degrees between 0 and 360 degrees is 328 degrees.

Meridians that are opposite each other on the globe are called "antimeridians." For example, the Prime Meridian (0° longitude) and its antimeridian at 180° longitude are directly opposite one another. Antimeridians are significant in navigation and mapping, as they represent the same line of longitude but on opposite sides of the Earth.

A downward movement of a block of material along a curved surface is called "sliding" or "slump." This process typically occurs when gravitational forces overcome the frictional forces holding the material in place, causing it to move along the slope of the curved surface. Depending on the context, it may also be referred to as "mass wasting" in geological terms.

An irregular quadrilateral has no lines of symmetry. This is because its sides and angles are not equal, meaning it cannot be folded in half to create two identical halves. Each irregular quadrilateral is unique in shape, further ensuring asymmetry.

Finding a right-side-up cross in your house is often interpreted as a symbol of faith, protection, and blessing. Many people associate it with positive energy, spiritual guidance, or a reminder of their beliefs. It can be viewed as a sign of safety and comfort within one's home. Ultimately, its significance can vary based on personal beliefs and cultural context.

Rotational management is a strategic approach where employees rotate through different roles or departments within an organization. This practice helps develop a diverse skill set, enhances collaboration, and fosters a deeper understanding of the company’s operations. It can also aid in talent development and succession planning, as employees gain varied experiences and insights. Overall, rotational management aims to improve employee engagement and organizational flexibility.

To find the height of the top of the ladder from the ground, we can use the Pythagorean theorem. In this case, the ladder forms a right triangle with the height (h) of the ladder against the wall and the distance (10 ft) from the wall. The equation is ( h^2 + 10^2 = 13^2 ). Solving for h, we get ( h^2 + 100 = 169 ), so ( h^2 = 69 ) and ( h \approx 8.31 ) ft. Thus, the top of the ladder is approximately 8.31 ft from the ground.

To load regular 30 for a Smart device, first, purchase a Regular 30 load from an authorized retailer or through the Smart app. Then, you can load it onto your SIM card by following the instructions provided, typically involving dialing a specific code or using the app's interface to confirm the transaction. Ensure that your device is connected to the internet or has sufficient signal strength to complete the loading process. Once loaded, you should receive a confirmation message indicating that your balance has been updated.

To find the x-coordinate of the vertex of a quadratic equation in standard form, which is (y = ax^2 + bx + c), you can use the formula (x = -\frac{b}{2a}). Here, (a) and (b) are the coefficients from the equation. Simply plug in the values of (a) and (b) into the formula to calculate the x-coordinate of the vertex.

Degrees in shapes refer to the measurement of angles within geometric figures. A full circle is divided into 360 degrees, and various shapes have specific angle measurements that contribute to their properties. For example, a triangle's angles always add up to 180 degrees, while a quadrilateral's angles sum to 360 degrees. Understanding degrees helps in analyzing and constructing shapes in geometry.

Yes, the term "isosceles" can be used to describe a triangle. An isosceles triangle is defined as a triangle that has at least two sides of equal length. This characteristic also means that the angles opposite those equal sides are congruent, making isosceles triangles a specific type of triangle based on their side lengths and angle properties.

A 25-sided 3D shape is called a "icosikaipentagon" or "icosikaipentagonal prism" if it has two 25-sided faces and rectangular lateral faces. The term "icosikaipentagon" specifically refers to the 25-sided polygon, while the prism term indicates its three-dimensional structure. In general, polyhedra can have various names based on their faces and geometrical properties.

Three main characteristics of parallel structures are: 1) Consistency in Form: Parallel structures maintain the same grammatical form within a sentence or list, enhancing clarity and rhythm. 2) Balanced Elements: They create a sense of balance by presenting ideas of equal weight or importance, making the writing more persuasive and engaging. 3) Increased Emphasis: By using parallelism, writers can emphasize key points or themes, as the repetition of structure draws attention to the ideas being presented.

To find the volume of a rectangular box, you multiply the area of the base by the height. Given that the base area is 15 square inches and the height is 12 inches, the volume is calculated as follows: Volume = Base Area × Height = 15 sq in × 12 in = 180 cubic inches. Therefore, the volume of the box is 180 cubic inches.

To find the midpoint of a line segment with endpoints (8, -3) and (-5, -9), use the midpoint formula: ((x_1 + x_2)/2, (y_1 + y_2)/2). Plugging in the values, we get: ((8 + (-5))/2, (-3 + (-9))/2), which simplifies to ((3/2, -6) ). Thus, the midpoint is ((1.5, -6)).

The second dress circle in a theater, also known as the "upper circle," is a seating area located above the first dress circle and below the balcony. It typically offers a more elevated view of the stage compared to the lower dress circle, making it popular among patrons who want a broader perspective of the performance. The seating in this area can vary in comfort and pricing, often being less expensive than the first dress circle while still providing a good view.
