Answer 2

Answer:

Three books of thickness 18mm, 13mm, and 7 mm are piled on top of each

What is the total thickness of the piles. The total thickness is 3.8 cm or 3 cm 8 mm.

Step-by-step explanation:

The total thickness of the pile is equal to the sum of the thickness of each of the books.

We have the thicknesses as follows:

7 mm, 13 mm, and 18 mm

Adding the thicknesses we have:

= 7 + 13 + 18 = 38 mm

We need to express it in cm.

The conversion is given by:

1 cm = 10 mm

Converting this we have:

38/10 = 3.8 cm

Writing this in cm and mm we have:

3 cm and 8 mm.
