Question

Length, breadth and height of a cuboid are 10 cm, 9 cm and 4 cm respectively. What is the minimum number of such cuboids that will be required to make it a cube ?
Pls give the explanation too.​

Answer 1

Answer:

First of all no dimensions of the cube are given so we have to decide on what minimum dimension cube we will form by using L of 4cm B of 3cm and H of 2cm dimension cuboid.

Volume of cuboid L*B*H=4*3*2=24

So let's assume we need a cube of a=12cm (LCM of 4,3,2)

Now volume of cube will be =L*B*H=12*12*12=1728

No of cuboids that can fit in the cube will be=

Volume of cube/Volume of cuboid=1728/24=72

Minimum no. Of cuboids needed to form a cube 72
