Question

Shishir is making a cube of side 6cm using cubes of side 2cm. How many such cubes are needed.

Answer 1

total volume of the bigger cube = volume of the small cubes

Volume of bigger cube= 6x6x6 =216 cm³

Volume of smaller cube = 2 x 2 x2 = 8 cm³

Required number of cubes = 216/8 = 27

So 27 cubes is needed
