**Question:**

**How many small cubes with edge of 20 cm each can be just accommodated in a cubical box of 2 m edge?**

**(a) 10 **

**(b) 100 **

**(c) 1000 **

**(d) 10000**

**Solution:**

The correct answer is option **(c) 1000**

**Explanation:**

We know that, the volume of cube is (side)3

Therefore, the volume of each small cube is (20)3

= 8000 cm3

When it is converted into m3, we get

V = 0.008 m3

It is given that, the volume of the cuboidal box is 23 = 8 m3

Now, the number of small cubes that can be accommodated in the cuboidal box is

= 8/ 0.008 = 1000
