Question

Parikshit makes a cuboid of plasticine for side 5 cm 2 cm 5 cm. how many such cuboids will be need to form a cube?

Answer 1

Hey bro here your answer

Given that Parikshit makes a cuboid of plasticine of sides 5 cm, 2 cm, 5 cm.
Now, we have to find l.c.m. of the sides of cuboids to get the side of cube.
Then, l.c.m. of 5, 2, 5 = 10.
Therefore, each side of the cube will be 10 cm.
Now, the volume of the cuboid is = (5*2*5) cubic cm = 50 cubic cm.
and, the volume of the new cube is = (10*10*10) cubic cm = 1000 cubic cm.
Therefore, he need (1000/50) cuboids, i.e., 20 cuboids.

I hope it's help you
