Chapter 1, Problem 1.67P

a)

Interpretation Introduction

Interpretation:Volume of water (in gallons) that is required to fill pool to average depth of $4.8\text{ ft}$ is to be determined.

Concept introduction: Density is defined as mass per unit volume. It is denoted by $d$ . The expression to calculate density is as follows:

  $d=\frac{M}{V}$

Where,

• $d$is the density.
• $M$is mass.
• $V$is volume.

b)

Interpretation Introduction

Interpretation:Mass of water (in $\text{kg}$ ) in pool is to be determined.
