Question

Parikshit makes a cuboid of plasticine of sides 5cm, 2cm and
5cm. How many such cuboids will he need to form a cube.​

Answer 1

Step-by-step explanation:

L.C.M. of 5 and 2 gives the dimension of the cube to be formed.

L.C.M. of 5 and 2 is 10

Volume of cuboid = 5 × 5 × 2 = 50 cm³

Volume of bigger cube = 10³ = 1000cm³

Number of cuboids required to make the bigger cube =

( Volume of cube ) / ( Volume of a cuboid )

1000 / 50 = 20 answer.

Thanks for the question. .
