Chapter 3, Problem 106E

Interpretation Introduction

Interpretation:

A rectangular block of iron $4.60\mathrm{ }\mathrm{c}\mathrm{m}\mathrm{ }\mathrm{x}\mathrm{ }10.3\mathrm{ }\mathrm{c}\mathrm{m}\mathrm{ }\mathrm{x}\mathrm{ }13.2$ cm has a mass of 4.92 kg. Its density in g/cm³ is to be calculated.

Concept introduction:

Commonly, two variables such as mass (m) and volume (V) can be described as directly proportional one on other by the expression m α V. Besides, the term density is defined by mass of a substance per unit volume and denoted by the ‘D’ symbol.
