Question

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

Answer 1

Answer:

1000

Step-by-step explanation:

Volume of cube = (side) ^3  or a ^3

Volume of each small cube =  20^3  = 8000cm^3  = 0.008m^3

Now, volume of the cubical box = 2^3  = 8m^3

 

Therefore, no. of small cubes, that can just be accommodated in the cubical box =  

Vol.ofcubicalbox       8

                          =  _____ = 1000

Vol.ofsmallcube ​  0.008

Answer 2

Answer:

Volume of cube = (side)³ or a³

Volume of each small cube = 20³ = 8000cm³

= 0.008m³

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

Therefore, no. of small cubes, that can just be accommodated in the cubical box

= Volume of cubical box/Volume of small cube

= 8/0.008

= 1000
