Answer: 149 cm^3
To find the volume for a cube, the formula is V = a^3, where a = length of one side.
Smaller cube:
a = 3
(3)^3, or 3 x 3 x 3
= 27 cm^3
Larger cube:
a = 5
(5)^3, or 5 x 5 x 5
= 125 cm^3
To find the volume of the entire sculpture, add the volumes of each of the cubes.
27 + 125
= 149 cm^3
