I need to do a project to figure capacity volume of a stationary cabinet with three shelves. I am confused about how to figure this with the shelves.

3 answers

consider each shelf as a small solid with width and depth and thickness. Then you can figure its volume and subtract it from the inside volume of the stationery cabinet.
Is capacity done the same way? I am confused about the difference between Volume and capacity. Thanks so much for your help!
volume is the same as capacity.

"capacity volume" is redundant
