Which box is cheaper per cubic unit? Type A or B
To calculate the volume of each box, you need the dimensions of each box. Once you have the volume of each box, you can find the unit price by dividing the price by the volume in cubic inches.
For example, if Box A costs $5 and has a volume of 100 cubic inches, the unit price would be $5 / 100 in3 = $0.05/in3.
You would then compare the unit prices of both boxes to determine which one is cheaper per cubic inch.
