Question: Edmund makes a cube using eight small cubes. 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?

Solution: The correct answer is 184.

8 x 2 = 16 – 16 x 3 = 48 – 48 x 4 = 192

192-8=184
