Answer 1

Answer:C:20

Explanation:

We just took test on edge

Answer 2

C.20 square ft

Explanation:

We are given that

Height of triangular prism=6 ft

Rectangular face of triangular prism is called lateral face of triangular prism.

Length of lateral face,l=8 ft

Breadth of lateral face,b==2.5 ft

We have to find the area of one of the lateral face of the triangular prism.

We know that

Area of rectangle=
`l* b`

Area of lateral face of triangular prism=
`8* 2.5`square ft

Area of lateral face of triangular prism=20 square ft

Hence,option C is true.
