The post office is now calculating the volume of packages to determine the shipping cost. If a box measure 8 1/2 inches long, 5 1/4 inches wide, and 7 inches high, what is its volume?
Explanation: The volume of a rectangular box can be measured as follows: volume = length* width * height
From the givens we have: length = 8.5 in width = 5.25 in height = 7 in
Substitute with the givens in the above equation to get the volume as follows: volume = length * width * height volume = 8.5 * 5.25 * 7 volume = 312.375 in²
