Answer 2

Answer:

No. of cuboids needed = vol of cube/ vol of cuboid = 10*10*10/5*5*2=100/50=20

Step-by-step explanation:

Given that parikshit makes cuboid of plasricine plastic of side 5cm 2cm 5cm

Now, we have to find l.c.m. of the side of cuboid to get the side of cube.

Then l.c.m. of 5,2,5 = 10

Therefore, each side of the cube will be 10cm.

Now, the valume of cuboid is = ( 5*2*5) cubic cm = 50 cubic cm

and, the volume of new cuboid is = (10*10*10) cubic CM = 1000 cubic cm

therefore, he needed ( 1000/50) cuboid, i.e.,20 cuboid
