Question

In a stack there are 4 books each of thickness 24mm and 6 paper sheets each of thickness 0.015mm. What is the total thickness of the stack in the standard form?

Answer 1

The total thickness of the stack is 9.6075 × 10⁻¹ mm.

Step-by-step explanation:

Thickness of each book is 24 mm

Then, the thickness of 4 books

= (4 × 24) mm

= 96 mm

Thickness of each paper sheet is 0.015 mm

Then, the thickness of 5 paper sheets

= (5 × 0.015) mm

= 0.075 mm

So, the total thickness of 4 books and 6 paper sheets

= (96 + 0.075) mm

= 96.075 mm

This result can be written in standard form as

9.6075 × 10⁻¹ mm
