The formula for volume is length × width × height, so this is the same as area of cross section × height. So, if the base of the rectangular prism (the cross section) has an area of 48 square feet, then 48 × the height = 192 cubic feet. Working backwards, we can find out the height (h will stand for height): 48×h=192 h=192÷48 h=4 Therefore, the height of the rectangular prism is 4 feet
