Question

2s2+4sh, where side s is side length of the square base and h is the height of the prism. What is the surface area in square feet of a rectangular prism with a square base where s=4 feet and h=6

Answer 1

The surface area is 128 square feet

Explanation:

Given the formula above, we want to calculate the surface area of the rectangular prism

All we have to do here is to make substitutions

we substitute s = 4 ft and h = 6 ft

Thus, we have that;

2s^2 + 4sh

= 2(4)^2 + 4(4)(6)

= 32 + 96 = 128 square feet
