# How many cubes of side 3 cm are required to build a cube of side 15 cm?

Answer :

Given:

side of small cube = 3cm

side of large cube = 15cm

volume of small cube = (3)^{3}

= 27

volume of large cube = (15)^{3}

= 3375

Number of required = volume of large cube/ volume of small cube

N = 3375/27

N = 125

Number of cubes required = 125
