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.

Answer
Volume of cuboid=5*2*5=50 In order to form a cube we will take the LCM of 5 2 and 5=10 Thus 10*10*10/50=20 cuboids
Answer

Length of cube will depend upon the lcm of the sides of cuboid, i.e. lcm (5,2,5 ) = 10 cm.

So now, no of cuboids required = Vol of cube / Vol of cube = 10*10*10 / 5*2*5 = 1000 / 50 = 20 cuboids

Answer

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

Answer

The volume of each cuboid = 5 x 5 x 2 (lbh) = 50 cu cm

​volume of cube = l x l x l = 10 x 10 x 10 = 1000 cu cm

no. Of cubes required = 100/50 = 20​

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

The volume of each cuboid = 5 x 5 x 2 (lbh) = 50 cu cm

​volume of cube = l x l x l = 10 x 10 x 10 = 1000 cu cm

no. Of cubes required = 100/50 = 20​

Answer
Side of cube to be formed = lcm of sides of cuboid , lcm of 2,5,5 =10 cm, now volume of this cube = 10×10×10=1000 cucm, now let n be the no of cuboid required to make perfect cube. thus n× vol. of cuboid = volume of reqd cube. or. n×5×5×2 =1000 , or, 50n = 1000 , or n = 1000/50 = 20 nos (ans)
