A measurement expressed to three significant figures includes three digits that contribute to its precision, which may include leading zeros but excludes trailing zeros unless they are after a decimal point. For example, the number 0.00456 would be expressed as 4.56 × 10^-3 in three significant figures. Similarly, a measurement like 1500 could be expressed as 1.50 × 10^3 if it is intended to be three significant figures.
As expressed, three.
To calculate the product of 1000 and 003 57 m (which is 3.57 m), we first note that 3.57 has three significant figures. Multiplying 1000 by 3.57 gives 3570. However, since 1000 has only one significant figure, the final result should also be expressed with one significant figure, resulting in 4000 m (rounded to the nearest thousand).
To three significant figure, 483.54 becomes 484. The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". Expressed in Scientific Notation, 484 becomes 4.84 x 102.
The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". The first figure to be discarded is '6' and as this is greater than 5 then the previous figure (4) is increased by 1 (to 5). 29.46 when rounded off to three significant figures is 29.5.
There are three significant figures in the measurement 245.

To determine the precision for a measurement of 120 meters, you need to consider the context of the measurement. Precision refers to the degree of refinement in a measurement, often indicated by the number of significant figures. If the measurement is given as 120 with no decimal places, it typically has three significant figures, suggesting that the value is precise to the nearest meter. If it were expressed as 120.0 meters, it would have four significant figures, indicating greater precision.
Three - the first two zeros are placeholders.
