Question

A book is 5 cm thick and each cover is 1.5mm thick . HOW thick is the book without its covers?

Answer 1

Answer:

4.85 cm

Step-by-step explanation:

Thickness of book without cover = 5cm - 1.5mm

= 5cm - 0.15cm

= 4.85cm

Answer 2

Answer:

4.7cm

Step-by-step explanation:

1. THICKNESS OF THE BOOK IS 5CM
2. THICKNESS OF THE COVER IS 1.5MM. SO CONVERT 1.5MM TO CM. 1MM = 1OCM WHICH GIVES 1.5/10 = 0.15CM
3. THE BOOK IS COVERED WITH TWO SIDES SO 0.15+0.15=O.3
4. NOW SUBRACT THE THICKNESS OF THE BOOK FROM THE THICKNESS OF COVER
5. 5 - 0.3 = 4.7cm
