What is the correct answer for the calculation of a length (in cm) with measured numbers (28.58 cm3 ) / [(24 cm) x (8.02 cm)]?
When adding or dividing measured numbers, we don’t count significant figures. Instead, we look at the precision of the measured numbers. The answer can only be as precise as the least precise measurement.
