Question

A rectangular prism has a length of 5 centimeters, a width of 5 centimeters, and a height of 10 centimeters. The surface area of this prism is 250 square centimeters.

True or False

Answer 1

surface area of a prism = 2(xy) + 2(xz) + 2(yz)

In this case, x = 5, y = 5, and z = 10:
SA = 2(5*5) + 2(5*10) + 2(5*10)
SA = 50 + 100 + 100
SA = 250 True

Answer 2

false
