Answer 1

Answer:

1) he appropriate unit for measuring area of a book is cm^2

2)1 km^2 = 10^6 m^2

3) 1 m^2= 10^4 cm^2

4) 1 m^3 = 10^6 cm^3

5) 0.02 cm= 0.0002 m

Explanation:

Answer 2

1) appropriate unit for measuring area of book : cm²

2) value of 1 square kilometre in terms of square metre: 10⁶ m²

3)1 m2 = 10n cm2  the value of ‘n’ is 4

4)the value of 1 cubic metre in terms of cubic centimetre is 10⁶ cc

5) 0.02 cm = 0.0002 metre
