Answer:
4.5 cubic ft.
Step-by-step explanation:
From the given figure is clear that the base of the triangular prism is a right angle.
Area of a right angle is
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
We know that,
12 inch = 1 ft
18 inch = 1.5 ft
So, area of triangular base is
[tex]A=\dfrac{1}{2}\times 1.5\times 2=1.5[/tex]
Volume of triangular prism is
[tex]V=A\times h[/tex]
where, A is base area of h is height of the prism.
[tex]V=1.5\times 3[/tex]
[tex]V=4.5[/tex]
Therefore, the volume of the triangular prism is 4.5 cubic ft.
