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

पर्याय

  • 10

  • 100

  • 1000

  • 10000

MCQ

उत्तर

1000

Explanation:

Volume of cube = (Side)3

Volume of each small cube = 203 = 8000 cm3 = 0.008 m3

Now, volume of the cubical box = 23 = 8 m3

∴ Number of small cubes, that can just be accommodated in the cubical box

= `"Volume of cubical box"/"Volume of small cube"`

= `8/0.008`

= 1000
