Type: MCQ-numerical-Medium-Class 11
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?
A
0.0855 m³
B
0.08554 m³
C
0.08554 m²
D
0.08554 cm³
Correct Answer
Option A
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).
