Tick (✓) the correct answer:
How many cubes of 10 cm edge can be put in a cubical box of 1 m edge?
(a) 10
(b) 100
(c) 1000
(d) 10000

Answer 1

(c) 1000

Volume of the smaller cube$=(10cm{)}^3=1000c{m}^3$
Volume of box$=(100cm{)}^3=1000000c{m}^3$ [1 m = 100 cm]
∴ Total no. of cubes $=\frac{100\times 100\times 100}{10\times 10\times 10}=1000$
