Question

Samuel uses cubes of the same size as the small cubes to make a cuboid twice as long, three times as wide and four times as high as Edmund's cube. How many more cubes does Samuel use than Edmund?

Answer 1

23 more cubes

Explanation:

If it's 2 times as long, the length is 2

If it's 3 times as wide, the width is 3

It it's 4 times as high, the height is 4

2 · 3 · 4 = 24, which is 23 more than 1
