Chapter 4, Problem 119A

Solution

Interpretation : The sheets of paper that would the sheet of gold mentioned in problem 118 covers are to be calculated.

Concept Introduction : The dimensional analysis moves or converts from one unit to another by using conversion factors in a systematic method. A conversion factor is a ratio of comparable values with various unit types.

The sheets of paper that would cover the sheet of gold are $54726.36$ papers.

Given information:

The area obtained from problem 118 is $0.33\times {10}^8{\text{cm}}^2$ .

A piece of paper has an area of $603{\text{cm}}^2$

Explanation:

To find the sheet of gold, divide the area obtained from the problem by the area of the paper.

  $\frac{0.33\times {10}^8{\text{cm}}^2}{603{\text{cm}}^2}=54726.36$
