2 identical number of cubes are show in the picture. The edge length of these number cubes is 3 centimeters. What is the combined volume of the 2 number cubes in cubic centimeters?

The volume of a cube is calculated by V = s^3, where s is the edge length of the cube.

For a cube with an edge length of 3 centimeters, the volume is:
V = 3^3 = 27 cubic centimeters

Since there are 2 identical number cubes, the combined volume of the 2 cubes is:
27 + 27 = 54 cubic centimeters

Therefore, the combined volume of the 2 number cubes is 54 cubic centimeters.
