Answer 2

Answer:

4.7 cm

Step-by-step explanation:

First step: As a book has 2 covers, one in front and other in back, add 1.5 + 1.5 = 3 mm

Second step: Convert 5 cm into mm by multiplying (5 x 10 = 50 mm)

Third step: Subtract 50 mm with 3 mm and you get 47 mm

Final step: Convert 47 mm into cm by dividing (47 / 10 = 4.7 cm)
