Help please!!! The back of Nico's truck is 7 feet long, 4 feet wide, and 8 feet tall. He has several boxes of important papers that he needs to move.
Each box of papers is shaped like a cube, measuring 1 foot on each side.
How many boxes of papers can Nico pack into the back of his truck? Show your work.

I got 224 as my answer but I don’t think that’s correct
