This large cube sculpture at the University of Michigan is made of steel. Even though it is extremely heavy, students can walk by and spin the cube very easily. Each side of the cube measures 15 feet across.

The volume of a cube is calculated by multiplying the length of one side by itself three times (V = s^3). Therefore, the volume of this cube would be 15 feet x 15 feet x 15 feet, which equals 3,375 cubic feet.
Answer: D) 3,375 ft³.
