Perimeter
The perimeter of a polygon is the sum of the lengths of all its sides.
What is the perimeter of a square having side-length 74 cm? Since a square has 4 sides of equal length, the perimeter of the square is 74 + 74 + 74 + 74 = 4 × 74 = 296.
One way to find the surface area of a rectangular prism, is to find the area of each side.
Say it has a:
length of 4
Width of 2
Height of 2
multiply height and width = 4x2(for the fact of the opposite side)= 8
next comes length and width= 8x2= 16
finally, do length and height=8x2= 16
so you add them all together, and you get a surface area of 40(inches, centimeters, or whatever the unit of measurment is)
To find the surface area of a rectangular prism, one would multiply the length by its width by its height. So, Surface Area = b x w x h. This equation would probably come up in a Google search, as any similar equations you may need would.
SA= B (area of base) + one side of base* 1/2 l (1/2 lateral height) *4
The surface area of a cylinder could be found by by adding area of bottom and area of the whole wall of cylendre
u get 1/2 an d mulitiply it by the base and the height
This is the same as the surface of a square column.
Add the area of the two ends to four times the area of one of the sides.
do the top width and length then the
side the width and height
then the front length and height
add them together
then multiply by 2
2LW + 2LH + 2WH
depends on how big it is
the defnition of find the surface area of triangular prism and cylinder
surface area of a rectangular prism is the formula: 2lw+2wh+2lh
To find the surface area of an equilateral triangular prism you take the area of the rectangular sides and the triangular bases and add them up and your done.
You will need to find the surface area of each face and add them together.
The Surface area of a triangle = 0.5*base*height The volume of a prism = area of its cross-section*length
Surface Area = 2 × Base Area + Base Perimeter × Length
get a maths book!!
Find the area of each face and add them all up.
It depends on the size of the triangular prism, but depending on the side of the prism you use the triangle area formula to find it or the rectangle area formula to find it.
Work out the surface area of its 6 faces individually and then add them together
Squared. When you find surface area, you are only finding the area of the shapes that make up the three-denominational shape.
It is not possible. For example, the prism could be tall and thin, or short and thick, and either way have the same surface area.
