Question

The base of a rectangular prism has dimensions of 2 feet by 3 feet.

If the height of the rectangular prism is 12 feet, find the number of square feet in its total area

Answer 1

The total surface area of this prism would be 120 square feet.

Answer 2

132 square feet.

Explanation:

The surface of area of a rectangular prism is defines ad

`S=2wl+2lh+ 2wh`

Where

`w= 2ft\\l=3ft\\h=12ft`

If we replace all given vales in the expression, we would have

`S=2(2)(3)+2(3)(12)+ 2(2)(12)=12+72+48=132`

Therefore, the surface of the rectangular prism is 132 square feet.
