Question

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

Answer 1

Answer:

2

Step-by-step explanation:

Volume of cuboid=l*b*h

=length=5

=breath=2

=height=5

Volume =50cm²

Volume of cube = a³

No. of cuboid required =x

Hence n*50=x³

Now n*50 must be perfect cube

n*50=n*2*5*5

So minimum value of n = 2*2*5 = 20

Hense, the number of cuboid will be needed to form a cube is 20
