Question

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

Ans) Dimersion of cubeid 5cm x 2cm x 5cm

value of cuboid = L x B x H
=5x2x5
=50cm3

cube least length ofcube=10cm

value of cube=a3
=(10cm)3
=1000 cm3

So, no of cuboid reqd to make a cube =1000/50
= 20 culboid​

Answer 1

Dimersion of cubeid 5cm x 2cm x 5cm

value of cuboid = L x B x H

=5x2x5

=50cm3

cube least length ofcube=10cm

value of cube=a3

=(10cm)3

=1000 cm3

So, no of cuboid reqd to make a cube =1000/50

= 20 culboid

Answer 2

Answer:

Therefore, he need (1000/50) cuboids, i.e., 20 cuboids. Answer: Length of cube will depend upon the lcm of the sides of cuboid, i.e. lcm (5,2,5 ) = 10 cm.
