Find the Surface Area

Find the surface area of the rectangular prism.

Find the Surface Area

Find the area of each face.

top and bottom: 2(ℓw) = 2(8 × 4) or 64

front and back: 2(ℓh) = 2(8 × 3) or 48

two sides: 2(wh) = 2(4 × 3) or 24

Add to find the surface area.

Answer: The surface are is 64 + 48 + 24 or 136 square centimeters.
