NEET Physics Significant Figures MCQ Question
Type: MCQ-numerical-Medium-Class 11
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?
A
0.0856 m³
B
0.08559 m³
C
85.6 m³
D
85.59 m³
Correct Answer
Option A
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.
