Question

Parikshit makes a cuboid of plasticine of 5 cm,2cm,5cm.how much such cuboids will he need to form a cube?
​

Answer 1

Step-by-step explanation:

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.

Answer 2

Answer:

No. of cuboids that he will he need to form a cube is 20.

Step-by-step explanation:

Given:

• Parikshit makes a cuboid of plasticine of 5 cm,2cm,5cm.

Need to find:

• No. of cuboids that he will he need to form a cube.

Explanation:

As we know that,

LCM of 5,2 and 5 = 10

Therefore,

Side of the required cube = 10cm

NOW,

As we know that,

No. of cuboid required to make a cube = volume of cube/volume of cuboid

=> 10×10×10/5×2×5

=> 20

Hence,No. of cuboids that he will he need to form a cube is 20.
