NEET Physics Significant Figures MCQ Question
The length, breadth, and thickness of a rectangular sheet of metal are given as 4.234 m, 1.005 m, and 2.01 cm respectively. What is the volume of the sheet expressed with the correct number of significant figures?
0.0855 m³
0.08554 m³
0.08554 m²
0.08554 cm³
Correct Answer
Detailed Explanation
To calculate the volume, convert all measurements to the same unit and then multiply. The thickness is converted to meters (2.01 cm = 0.0201 m). The answer should be rounded to the least number of significant figures in the measurements, which is 3 (from 2.01).
