The answer of multiplication problem 2 .0000 × 2 .00 × 0 .0020 must be expressed to the correct number of significant figures. Concept Introduction: Whenever a measurement is made, the significant figures in the measured quantity give the actual measurement. For this the significant figures should be recognized first. The significant figures may be non-zero digit and zero digit. But Zero may be or may not be a significant figure. The number of significant figures in the answer after solving a multiplication or division problem is same as the number of fewest significant figures present in the measurement.

Answer to Problem 2.49EP
When the problem 2.0000×2.00×0.0020 is solved, the answer (0.0080) obtained will have two significant figures.
Explanation of Solution
The number of significant figures in the answer after solving a multiplication or division problem is same as the number of fewest significant figures present in the measurement. In the problem, 2.0000×2.00×0.0020, 2.0000 has significant figure of five, while 2.00 has three significant figures and 0.0020 has two significant figures. Hence the lowest significant figure from the above measurement is two, so the answer obtained will have two significant figures.
The answer will have two significant figures, if the problem 2.0000×2.00×0.0020 is solved.
