A rectangular prism measures 8 inches in width 4 inches in height 12 inches in length. What is the surface area of the prism?

Answer 1

The rectangular prism has 6 sides. We need to calculate the area of each side and then add them up.

Width X Height X 2 = 8 x 4 x 2 = 64

Width X Length X 2 = 8 x 12 x 2 = 192

Height x Length X 2 = 4 x 12 x 2 = 96

The surface area of prism is 64 + 192 +96 = 352

The end
