Question

How many cubes can be formed of side 2cm from a cube of side 6cm?

Answer 1

vol of cube=a^3

vol of CUBE 1 =vol of cube 2 ×no. of cubes

no. of cubes = vol of cube 1 ÷ vol of cube 2

=6×6×6÷2×2×2

=216÷8=27

Answer 2

Dimensions of 1st cube = 2cm × 2cm × 2cm

Dimensions of 2nd cube = 6cm × 6cm × 6cm.

According to the question ,

To find the number of cubes divide the dimensions of 1st cube from the dimensions of 2nd cube ,

$\implies\bold{\dfrac{6cm\times 6cm\times 6cm}{2cm\times 2cm\times 2cm} = 27.}$

$\therefore$ 27 cubes can be formed of side 2cm from a cube of side 6cm.
