if the volume of a cube shaped box is 729 cubic inches, how many 1 inch cubes could fit along one side?
Ronch [10]

Answer:

81 1-inch cubes

Step-by-step explanation:

Cube root of 729 is 9

9 x 9 = 81

Further explanation:

A cube has 3 measures (there are all the same) to solve for the volume. If the volume is 729, and it is a cube, you would solve for the cube root, because all the numbers are the same. Then, we would get 9. Now, since a cube is made up of faces, and each one is a square, we do 9 x 9 to get the area, which is the answer, because 1-inch cubes are literally just units.
