Question

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:Hello!

Least Length of Cube =10

Volume of cube =10^3=1000

Dimensions of cuboid =5*2*5

Volume of cuboid =5*5*2=50

So number of Cuboid required to make a cube =1000/50=20 cuboids

★ Thus, 20 cuboids of dimensions 5*2*5 are,required to make a cube

hope helped!!

Step-by-step explanation:

Answer 2

Answer:

20 CUBOIDS

Step-by-step explanation:

the sides of the cuboid are given as 5 cm , 2 cm and 5 cm

volume of the cuboid = 5 cm *2 cm *5 cm= 50 cm

for the prime factorization of 50, we have

50= 2 * 5 * 5

to make it a perfect cube , we must have

2 * 2 * 2 * 5 * 5 * 5

20 * ( 2 * 5 * 5 )

=20 * volume of the given cuboid

thus the required number of cuboids = 20
