Answer 2

Answer: When the dimensions are doubled, the volume is eight times the original volume.

Explanation:

Volume right now: 420 cm³

If we double all the dimensions, then the new specifications are 10, 14, and 24 inches respectively. This means that the new volume will be 3360cm³.

The relationship between the new volume and the old volume are: 3360/420 = 8

So the new volume is 8 times the original volume. Your answer is the last option
