Question

Find the surface area of the prism. Enter your answer in the box. A rectangular prism with dimensions 6 meters by 3 meters by 12 meters.

Answer 1

Given:

Dimensions of a rectangular prism are 6 meters by 3 meters by 12 meters.

To find:

The surface area of the prism.

Solution:

The surface area of a rectangular prism is:

`A=2(lb+bh+hl)`

Where, l is length, b is breadth and h is height.

Putting
`l=6,b=3,h=12`, we get

`A=2(6* 3+3* 12+12* 6)`

`A=2(18+36+72)`

`A=2(126)`

`A=252`

Therefore, the surface area of the prism is 252 square meters.
