A shipping company must design a closed rectangular shipping crate with a square base. The volume is 23040ft3. The material for the top and sides costs $6 per square foot and the material for the bottom costs $14 per square foot. Find the dimensions of the crate that will minimize the total cost of material.

The median of a data set is the measure of center that is found by adding the data values and dividing the total by the number of data values that is the value that occurs with the greatest frequency that is the value midway between the maximum and minimum values in the original data set that is the middle value when the original data values are arranged in order of increasing (or decreasing) magnitude
