Question

What is the volume of the triangular prism below?

Answer 1

4.5 cubic ft.

Explanation:

From the given figure is clear that the base of the triangular prism is a right angle.

Area of a right angle is

`Area=(1)/(2)* base* height`

We know that,

12 inch = 1 ft

18 inch = 1.5 ft

So, area of triangular base is

`A=(1)/(2)* 1.5* 2=1.5`

Volume of triangular prism is

`V=A* h`

where, A is base area of h is height of the prism.

`V=1.5* 3`

`V=4.5`

Therefore, the volume of the triangular prism is 4.5 cubic ft.
