NEET Physics Significant Figures MCQ Question
If the length, breadth, and thickness of a rectangular sheet of metal are 4.234 m, 1.005 m, and 2.01 cm respectively, what is the volume of the sheet in cubic meters to the correct number of significant figures?
0.0856 m³
0.08559 m³
85.6 m³
85.59 m³
Correct Answer
Detailed Explanation
The volume is calculated as length × breadth × thickness. Converting thickness to meters, we have 2.01 cm = 0.0201 m. The volume is 4.234 m × 1.005 m × 0.0201 m = 0.08559107 m³, rounded to four significant figures (matching the least precise measurement, 2.01 cm), giving 0.0856 m³.
