Question

How many cubes of side 3 cm can be cut from the cube of side 18 cm?

• A. 150
• B. 180
• C. 206
• D. 216

Answer 1

The correct option is D 216

Side of smaller cube = 3 cm
Side of bigger cube = 18 cm

Volume bigger cube = Number of cubes $\times$ Volume of smaller cube

Number of cubes = $\frac{Volumebiggercube}{Volumeofsmallercube}$
Number of cubes = $\frac{18\times 18\times 18}{3\times 3\times 3}$
​​​​​​​​​​​​​​Number of cubes = 216
