A rectangular prism has a base that is 5 cm by 7 cm and a height of 12 cm. If all dimensions are doubled, what happens to the volume?

The original volume is 5 × 7 × 12 = 420 cm³. Doubling each dimension gives a volume of 10 × 14 × 24 = 3,360 cm³. Since 3,360 ÷ 420 = 8, the volume becomes eight times the original volume, which matches choice D.
