Question

A right rectangular prism has a length of 2.5 feet, a width of 3 feet, and a height of 1.5 feet. Unit cubes with side lengths of .5 foot are added to completely fill the prism with no space remaining. What is the volume, in cubic feet, of the right rectangula prism?

Answer 1

The volume of the right rectangular prism is 11.25 cubic feet.

Step-by-step explanation:

The volume of a right rectangular prism is found by multiplying its length, width, and height. In this case, the length is 2.5 feet, the width is 3 feet, and the height is 1.5 feet. To find the volume, multiply these values together:

Volume = 2.5 ft * 3 ft * 1.5 ft = 11.25 ft³

Therefore, the volume of the right rectangular prism is 11.25 cubic feet.

Answer 2

The volume of the prism is given by:
volume=length×width×height
when the lengths were adjusted the new dimensions will be:
length=2.5+1=3.5
width=3+1=4 ft
height=1.5 +1=2.5 ft
thus the volume will be:
v=3.5×4×2.5
v=35 cubic feet
