Determine the number of significant figures in the measurement quantity: 6.010m^2

Our significant figures are 4

Explanation:

Our measure is 6.010 m²

Our significant figures are 4

1 significant figure before the decimal place → 6

3 significant figures after the decimal place 010

The significant figures in a measure are all the digits other than zero, the zeros that are located between different digits of zeros and the zeros that are to the right of a number different from zero

For example:

0.004 has 1 significant figure

0.40 has 2 significan figures

1.2 has 2 significant figures

1.02 has 3 significan figures
