is total thickness.​

Answer 1

Answer:

210.13 mm

Here is your explanation-

No. of books in the shelf= 7

Thickness of each book= 30mm

Total Thickness= 7 × 30

=210mm

No. of cardboards in the shelf= 5

Thickness of each cardboard= 0.026mm

Total thickness= 5 × 0.026

= 0.13mm

So, total thickness of books and cardboards =

210+ 0.13

=210.13 mm
