Explanation:

Given The length breadth and thickness of a block is measured to be 50 cm 2.0 cm and 1.00 cm . What is the percentage error in the measurement of volume? (A) 8% (B) 0.8% (C) 10% (D) 12.5%

• Given length, breadth and thickness of the block measured as 50 cm, 2.0 cm and 1.00 cm. We need to calculate percentage error.
• So we have Δl / l = 1/50  
•                              = 1/ 50 x 100
•                            = 2%
• Also Δb / b = 0.1 / 2 (least count is 0.1)  
•                  = 1 / 20 x 100
•               = 5%
• Also Δt / t = 0.01 / 1
•                  = 1 / 100 x 100
•                  = 1%

Now total percentage error = 2% + 5% + 1% = 8%
