Answer 2

(C)108 square feet

Explanation:

A net of triangular prism consists of two triangular and three rectangular faces.

The net attached is that of a right triangular prism.

Area of One Triangular Face =0.5 X 3 X 4=6 square feet

The rectangular faces are of dimension 4 ft by 8 ft, 5ft by 8ft and 3ft by 8 ft respectively.

Therefore:

Surface Area of the net =2(6)+(4X8)+(5X8)+(3X8)

=12+32+40+24

=108 square feet

The correct answer is C.
