Question

Rahul makes a cuboid of 5cm,4cm, and 2cm. how many such cuboid will be needed to form to cube.​

Answer 1

200 cuboides are needed to form a cube of 20cm side length.

Step-by-step explanation:

For a cube, all sides are need to be equal.

So, for cuboide we take the LCM of all sides of it, as 5cm, 4cm and 2cm. The LCM is 20.

In length side(5cm) we put 4 cuboides.

In breadth side(4cm) we put 5 cuboides.

In height side(2cm) we put 10 cuboides.

Now we have to calculate the total units to form this cube.

So, 4×5×10 = 200.

Hence,

200 cuboides are needed to form a cube of 20cm side length.
