Question

A book is 3.5 cm thick and each cover is 1.8 mm thick . how thick is the book without its covers​

Answer 1

1.8mm=0.18cm
3.5cm-0.18cm=3.32cm

Answer 2

Answer: 4.7 cm

Step-by-step explanation:

Because

1.5mm =0.15 cm ,

so both covers together would be 0.3 cm , subtract that from 5 cm,i.e.,

5 -0.3 = 4.7 cma book has two covers one at front and at back

so 1.5 +1.5 =3 mm

so 10 mm = 1 cm

convert 5 cm to mm as 5 * 10 = 50 mm

50-3 = 47 mm or 4.7 cm
