We don't know what the dimensions are, but any numbers that have a sum of 120 will work. Let's use 3, 4, and 10.
3 x 4 = 12 10 x 12 = 120
But if you double each dimension:
6 x 8 = 48 48 x 20 = 960 To find how much the sums changed:
960 / 120 = 8
The new volume is 8 times what it originally was! 960 in.
