Question

Please help me understand!Problem:Two identical number cubes are shown in the picture. The edge length of these number cubes is 3 centimeters.Question:What is the combined volume of the number cubes in cubic centimeters?A.27 cm^3B.18cm^3C.9 cm^3D.54 cm^3

Answer 1

The volume of a cube is given by

$V=l^3$

Since the lenght in this case is 3 cm, each cube has a volume of:

$V=(3)^3=27$

Now, the combined volume is the sum of the volume of each cube.

Therefore, the combined volume of the cubes is 54 cm^3.
