A hot air balloon contains 28 cu.cm of hot air in it. What is this volume expressed in cu. meters? [We come across several instances in our day to day life where it becomes essential to convert units from one system to another].
Mathematically, the problem is as follows:
28 cm^3 = ____ m^3 ?
28 cm^3 = 28 cm X cm X cm
= 28 X 1 cm X 1 cm X 1 cm
= 28 X (1/100)m X ...
Air balloon question is worked.
