Answer:
7200 cubic feet
Step-by-step explanation:
The volume of a prism can be found using the formula V = Bh, where B is the area of the base and h is the height. In this case the base is a triangle, and the area of a triangle can be found by the formula [tex]\frac{1}{2} bh[/tex]. Since the base is 20 and the height is 30, the area of the base is [tex]\frac{1}{2} (20)(30) = 300 ft^{2}[/tex]. So, now we know both the area of the base and the height of the prism, which was already given to us by the diagram (24 feet). And, all we have to now is to multiply them together! So:
V = Bh
V = 300(24)
V = 7200 [tex]ft{^{3} }[/tex]
Hope that helped! :)
