Answer:
The ratio of new volume to old volume is 24:1.
Explanation:
Multiplying width by 2 will double the volume; multiplying length by 3 will multiply that doubled volume by 3, making the new volume 6 times what it was. Then multiplying the height by 4 will multiply that volume by 4, so the end result is a volume 24 times the original.
The ratio of new volume to old is 24:1.
