Question
A cube of side 6 cm is cut into a number of cubes, each of side 2 cm. The number of cubes formed is
Options
6
9
12
27
Solution
27
Volume of the given cube = (6 × 6 × 6) cm3
Volumes of each small cube = (2 × 2 × 2) cm3
Number of cubes formed `="Volume of the given cube"/"Volume of each small cube"`
`=(6xx6xx6)/(2xx2xx2)`
= 27
