Question

There are different length measuring instruments in laboratory. For example wooden scale ( least count 0.1 cm), Vernier caliper ( least count 0.01 cm)and screw guage ( least count 0.001 cm)etc. Two students A and B performed an experiment to find volume of two identical cylindrical wooden block by measuring their diameters and heights. They used the formula V= π d²h/4. Q28.By taking more number of observations, which kind of error is reduced?
