How do you find the surface area of a sqaure prism?

Answer 1

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.

Answer 2

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)

Answer 3

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.

Answer 4

SA= B (area of base) + one side of base* 1/2 l (1/2 lateral height) *4

Answer 5

The surface area of a cylinder could be found by by adding area of bottom and area of the whole wall of cylendre

Answer 6

u get 1/2 an d mulitiply it by the base and the height

Answer 7

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.

Answer 8

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

Answer 9

depends on how big it is
