Measurement made in science lab must be as accurate as possible. Raj
measured the length of an iron rod and said it was 19.36 cm long, Kiara said
19. 29 cm and Dhruv said 19.58cm. The correct length was 19.33cm. How
much error was made by each of the boys? And who made the least error?

Answer:
The actual length of the iron rod = 19.33 cm
Ravi measured = 19.34 cm
Error = measured value - actual value
= 19.34 - 19.33 = 0.01 cm
Kamal measured = 19.25 cm
Error = 19.25 - 19.33
= -0.08 cm
Tabish measured = 19.27 cm
Error = 19.27 - 19.33
= -0.06 cm
hope this helps you
