Plzz help me it emergency......
Manu has a cuboid of side 10 cm 3 cm and 10 cm how many such cuboid will be needed to form a cube

Answer 1

Answer :

Volume of Cuboid = 10 * 3 * 10 = 300 cm^{3}

The Length of side of the cube will be a multiple of the sides of cuboid.

LCM of 10,3,10 :

5 * 2 * 3 = 30 = Side of the cube which can be formed.

To get Number of cubes can be formed ,

Divide the volume of cube by cuboid

Number of cubes = 30 * 30 * 30 / 300 = 90 Cuboids

Answer 2

Given sides of a cuboid are 10cm,3cm,10cm.

In order to get the side of a cube, we have to find the LCM of sides of cuboids.

LCM of 10,3,10 = 2 * 5 * 3 = 30.

Therefore side of each cube = 30 cm.

Now,

= > Volume of cuboid = (10 * 3 * 10) = 300 cm^3

= > Volume of new cube = (30 * 30 * 30) = 2700 cm^3.

Therefore,

The number of cuboids required to form a cube = 27000/300

= > 90.

Hope this helps!
