Question

parikshit makes a cuboid of plasticines of sides 5cm 2cm nd 5cm. how many such cuboid will he need to form a cube?

Answer 1

Let the number of cuboids required be ' n '

So Volume of Cube = n * Volume of Cuboid

Volume of cuboid = 5 cm * 2 cm * 5 cm = 50 cm³

The least length of the cuboid will be 10 cm.

Hence Volume would be 10³ = 1000 cm³

=> 1000 cm³ = n * 50 cm³

=> n = 1000 cm³ / 50 cm³

=> n = 20

Therefore the number of cuboids required are 20.

Hence solved !
