Question

How many cubes of side 2cm can be packed in a cubical boxof equal to 4 cm???
Please answer fast...

Answer 1

Volume of the cube box = a³ (where a = side)
= (4cm)³
= 64 cm³

Volume of a cube = a³
= (2cm)³
= 8 cm³

Number of cubes = $\frac{Area \:of\: cubical\: box}{Area \:of \:a\: cube}$

= 64 cm³/8 cm³
= 8 cubes
