Question

In a stack there are 5 books each of thickness 30 mm and 6 papers sheets
each of thickness 0.025 mm. What is the total thickness of the stack?​

Answer 1

Answer:

First of all there are

5 books thickness 30mm

6 sheets thickness 0.025 mm

If we count the total number of sheets

they are 5×6=30

Thickness of the sheets

= 30×0.025mm=0.75mm

Now for the thickness of books

5×30mm=150mm

Total thickness = Thickness of sheets + Thickness of book

=0.75mm+150mm

=150.75mm

hope this helps

Answer 2

ans is 150.15mm

explanation:

if there are 5 book each of thickness 30mm, then if we multiply 5 by 30 we will get 150,which is the thickness of 5 books. now if there are 6 paper sheets each thickness 0.025mm, then if we multiply 6 by 0.025 we get 0.15,which is the thickness of 6 paper. now if we add 150 and 0.15 together we will easily get the ans, which is 150.15 :)
