This is a triangular prism, so the volume is base times height. Area of the triangular base is half the base times the height.
8 * 5.2 / 2 = 20.8 in²
Take this a multiply by 12 and get 249.6 in3 ■

How do you estimate the square footage of a triangle?
One half of the Base (bottom line) x Height. Ex. Bottom length is 7 and the height is 5. 7 x 5 = 35. Divide by 2 = 17.5sq. ft.
Area of an isosceles right angled triangle?
The area of a right angled triangle would be .5 * length *width where the length is the height of the triangle. To find the height of the triangle, take the sine of 45 degrees, which is the degree of the angles other than the 90 degrees, and multiply it by the length of one of the two equal sides. The width of the triangle is the length of the bottom side.
When calculating area what are the similarities between triangles and parallelogram?
Parallelogram = Base*Height Triangle = 0.5*Base*HeightParallelogram = Base*Height Triangle = 0.5*Base*HeightParallelogram = Base*Height Triangle = 0.5*Base*HeightParallelogram = Base*Height Triangle = 0.5*Base*Height
How can you calculate the area of an object?
usually in a quadrilateral (four-sided shape) you multiply the height by width In a triangle, the height by width then divide by 2. This is because a triangle is mathematically always half the area of the rectangle. In a trapezium or trapezoid in some countries, its the top length added to the bottom length which is then divided by two multiplied by the length top to bottom. But always remember the height you multiply it with is the straight top to bottom length not the side length.
What do you mean by half of base times height in area of a triangle?
The area of a triangle is 1/2 x base x height. This means that you take half of the side on the bottom of the triangle and multiply it by the height from the base to the tip of the triangle. For example, if the base of the triangle is 4 cm and the height is 2 cm, then the area is: A = 1/2 x b x h A = 1/2 x 4 cm x 2 cm A = 2 cm x 2 cm A = 4 cm2
What is the area of a triangle with a bottom length of 3 yd?
Need to know the triangle's height to tell.
What is a height of a triangle?
The perpendicular distance from the base (either the longest side or the bottom) to the other corner
What is the area formula for a right triangle?
The answer is base times height divided by two or half base times height It's b x h divided by 2 It is the bottom of the triangle, times the height of the triangle (length from highest part, to lowest part) and then divide that number by 2. _______________________________________________________________ Base x Height x 0.5
What is the perimeter of a triangle that has sides of 7 inch by 8 inch and 9 inch?
The formula for area of a triangle is bh/2 b=base h=height /=divide so multiply the base(or the bottom) side by the height of the triangle, and then divide that by two.
What is the area of an equillatoral triangle?
The area of ANY triangle can be found using the formula: Area = Base of triangle * (1/2) * Height of triangle The height of a triangle is measured from the "bottom", or base of the triangle straight up to the top "corner". This measurement is inside the triangle. For example: An equilateral triangle has all 3 sides the same. (See the word equal?) Using your numbers, plug them into the formula and figure out what the area of your triangle is.

The base of a triangle is 8 cm. the triangle has a area of 28cm2 the height of the triangle is cm?
Area of Triangle = 1/2 base x height 28 = 4 x height height = 7 cms

What can be said about the base and height of a triangle?
That the area of a triangle = 0.5*base*height
What is another word for the height of a triangle?
Altitude is another word for a height of a triangle.
