Two identical number cubes are shown in the picture. The edge length of these number cubes is 3 centimeters.
What is the combined volume of the two number cubes in cubic centimeters?
54 cm3
18 cm3
9 cm3
27 cm3
...
The volume of a cube is calculated using the formula V = side length^3. Since the edge length of each cube is 3 cm, the volume of one cube is 3^3 = 27 cm^3. Since there are two cubes, the combined volume is 27 cm^3 + 27 cm^3 = 54 cm^3.
Therefore, the combined volume of the two number cubes is 54 cm^3.
