Question

What is the answer to this?

Answer 1

Answer:

Step-by-step explanation:

Each of the four sides of this triangular prism has height 8 m and base 12 m.  The area of each face this thus A = (1/2)(base)(height), or

A = (1/2)(12 m)(8 m) = 48 m^2.   The total side area is thus 192 m^2.

This is the surface area.  If we want to include the base area, that would be another (12 m)^2 , or 144 m^2.
