Answer:
8 feet
Step-by-step explanation:
The length can be found using the volume formula with the known values. The resulting equation can be solved for the unknown value.
__
V = LWH . . . . . volume of a prism is the product of its dimensions
108 ft³ = l×(3 ft)×(4.5 ft) . . . . . known values filled in
l = 108 ft³/(13.5 ft²) = 8 ft . . . . . . divide by the coefficient of length
The length of the prism is 8 feet.
