Question from kim, a student:

I am trying to find the formula to figure capacity in ounces for the following:

a rectangle 18" long, .75" wide, .75" deep ....

This is for an art project and the cost estimate. Thanks, Kim

Hi Kim,

The volume of your rectangular box is 18 × 0.75 × 0.75 = 10.125 cubic inches. I looked on a unit conversion site and found that 1 cubic inch is 0.5541125541126 US fluid ounces. Hence the volume of your box is 10.125 × 0.5541125541126= 5.61fluid ounces.
