Rahul make a cuboid of plasticine of sides 3cm x 3cm x 5 cm how many such cuboids will need to form a cube​

Answer 1

Answer:

Hey mate here is ur answer-

For this first we have to find the volume if the cuboid. It is 3 X 3 X 5 = 45cm^3.

Now we know that 45 is not a perfect cube.

Now, each side of cube will be the LCM of 3,3,5. = 15

So volume of cube=a^3=15^3=3375.

Now, cuboids needed will be= 3375/15

=75

He needs 75 cuboids.
