Question

a triangular prism is 20 yards long and has a triangular face with a base of 24 yards and a height of 16 yards . the other two sides of the triangle are each 20 yards.what is the surface area of the triangular prism?

Answer 1

The surface area of the triangular prism is 1664 square yards.

Step-by-step explanation:

Given that a triangular prism is 20 yards long and has a triangular face with a base of 24 yards and a height of 16 yards . the other two sides of the triangle are each 20 yards.

Surface area of the triangular prism:

The formula to determine the surface area of the triangular prism is

`SA=bh+Pl`

where base
`b=24` ,

height
`h=16`,

length
`l=20` and

Perimeter
`P=20+20+24=64`

Substituting these values in the above formula, we get,

`SA=(24* 16)+(64* 20)`

`=384+1280`

`SA=1664`

Thus, the surface area of the triangular prism is 1664 square yards.
