Use the formula for finding the volume of the right rectangular prism 2.5ft , 5 ft , 3.5ft

The formula for finding the volume of a right rectangular prism is:

Volume = length x width x height

So, for a right rectangular prism with dimensions 2.5ft, 5ft, and 3.5ft, the volume would be:

Volume = 2.5ft x 5ft x 3.5ft = 43.75 cubic feet

Therefore, the volume of the right rectangular prism is 43.75 cubic feet.
