Find the volume of the prism. A. 578.8 ft B. 552.9 ft C. 598.1 ft D. 591.5 ft

Elena L [17]

Answer:

591.5 $ft^{3}$

Step-by-step explanation:

Volume = length x width x height

Length = 13 ft. Because it is the same size has the height

Width = 7 ft.

Height = 13 ft.

13ft x 13ft x 7ft = 1,183 ft

BUT, that can't be the answer because we're solving a prism

So divide the volume.

1,183 divided by 2 equals 591.5
