4P - Fundamentals Of Physics

Question

Question: Spacing in this book was generally done in units of points and picas: 12 Points = 1 pica  , and  6 picas =1 inch. If a figure was misplaced in the page proofs by 0.80cm , what was the misplacement in (a) picas and (b) points?

Step-by-Step Solution

Answer

Answer

 

1. The misplacement of the figure is 1.9 picas.
2. The misplacement of the figure is.23 points

Step 1: Given data

The conversion factors given in the problem are listed as,

 6 picas = 1 inch

1 pica = 12 pints

Step 2: Understanding the concept of conversion factors

Typographical units are units of measurement used for typography or composition. The pica is a typographic unit of measure that corresponds to inches and feet.

 

Step 3: (a) Determination of misplacement in picas

Using the given conversion factors, the misplacement of the figure is calculated as: 

$$\begin{gathered} 0.80 cm =0.80 cm \left(\frac{1inch}{2.54 cm}\right)\times \left(\frac{6 picas}{1 inch}\right) \\ = 1.88 picas \\ \approx 1.9 picas \end{gathered}$$

 

Thus, the misplacement of the figure is 1.9 picas.

 

Step 4: (b) Determination of misplacement in points

Use the conversion factors to calculate the misplacement of the figure in points.

$$\begin{gathered} 0.80 cm =0.80 cm \left(\frac{1inch}{2.54 cm}\right)\times \left(\frac{6 picas}{1 inch}\right)\times \left(\frac{12 points}{1 picas}\right) \\ = 22.67 points \\ \approx 23 points \end{gathered}$$

 

Thus, the misplacement of the figure is 23 points.
