Question

A rectangular prism has dimensions of 21 , 2, and 72 in. (a) How many cubes with side lengths of 1 in. will fit into the prism? Explain. (b) How many cubes with side lengths of 21 in. will fit into the prism? Explain.

Answer 1

21 * 2 * 72 = 3024 cubes with side lengths of 1 inch will fit.

0 cubes with side lengths of 21 inch will fit. 2 is less than 21, so it can't fit in that dimension.
