Chapter 1, Problem 55E
Interpretation Introduction
Interpretation:
The mass of block of iron with given density and dimensions needs to be determined.
Concept introduction:
The density of the given sample is the mass of substance present per unit volume. It can be calculated from the following formula:
Here, m is mass and V is volume of the substance.
