Question

What is the surface area of the right rectangular prism with square bases

pictured below with measurements a = 5 cm, b = 8 cm?

Answer 1

210 cm²

Explanation:

SA = Ph + 2B

where SA = surface area

P = perimeter of the base

h = height of the prism

B = area of the base

SA = [(8 + 8 + 8 + 8)(5) + 2(5²) ]cm²

SA = 210 cm²
