Textbook Question
Chapter 1, Problem 11P
A block of gold has length 5.62 cm. width 6.35 cm, and height 2.78 cm. (a) Calculate the length times the width and round the answer to the appropriate number of significant figures. (b) Now multiply the rounded result of part (a) by the height and again round, obtaining the volume. (c) Repeat the process, first finding the width limes the height, founding it, and then obtaining the volume by multiplying by the length. (d) Explain why the answers don’t agree in the third significant figure.
