Question

how many small cubes having edges 20 cm can be accomodated in a cubical box having 4m edge?

Answer 1

Volume of one small cube = 20 x 20 cm = 400 sq. cm

Side if the larger cubical box = 4m = 400 cm

Volume of the larger cuboidal box = 400x 400 cm = 1,60,000 sq. cm

Amount of small cubes that can fit in the large box = 1,60,000 / 400 = 400 cubes

Hence, 400 small cubes can fit in the large box.

Hope it helps!
