Question

Explain why the surface area of a right prism can be found using the formula

A = ph + 2B
where p = the perimeter of the base, h = height and B = the area of the base.

Answer 1

ph : perimeter = 4 sides of the base; p*h = the area of the sides of that prism

B : 2 areas of the base = top and bottom

Answer 2

The Answer Is A = ph + 2B

A right prism consists of a rectangle and two undersides S night prism =

S rectangle + 2S base

the length of the rectangle is the circumference of the base which is P so A = ph + 2B
