A wooden block that is a rectangular prism is 12 inches long. Melinda cuts the wooden block along its length into 4 cubes. How long is each side of the cube?

I think 3 inches.

Right.

To find the length of each side of the cube, we need to divide the length of the rectangular prism by the number of cubes created.

In this case, the wooden block is 12 inches long and it is cut into 4 cubes. So, to find the length of each side of the cube, we divide 12 by 4.

12 รท 4 = 3

Therefore, each side of the cube will be 3 inches long.
