Mathematics for IGCSE & O level - Similarity (Section 1 - No. 5)

Three similar wooden boxes have heights in the ratio 3:4:5. What is the ratio of their volumes?

9:16:25

27:64:125

6:8:10

3:4:5

Since Volume scale factor = (length scale factor)^3, the ratio of volumes is 3^3 : 4^3 : 5^3 = 27:64:125
