Chapter 2, Problem 64E

Interpretation Introduction

Interpretation:

Mass and length are independent physical quantity while density and volume are dependent physical quantity.

The dimension of mass $=\left[M\right]$

The dimension of length $=\left[L\right]$

The dimension of density $=\left[M{L}^{-3}\right]$

The dimension of volume $=\left[L^3\right]$

Concept introduction:

Density is defined as the ratio of mass and volume.

$\text{Density}=\frac{\text{Mass}}{\text{volume}}$

To convert the unit of physical quantity, the unit conversion factor is used.

To determine: the density in pounds per cubic inch
