170.040 has six significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
A decminal place is simply the number of digits to the right of the decimal in a number. For instance, 37.5834 has four decimal places. In contrast, a significant figure is the number of digits on either side of the decimal place that can be counted as accurate in a calculation. Significant figures are used to determine how accurate a calculation is based on how accurate the measurements are. Significant figures are determined by counting the number of significant figures in the numbers given in a problem (usually in chemistry or physics) then using the lowest count found. Here's an example: "calculate the average velocity of a car that has travelled 45 km in 60 minutes." The number "45" has two significant figures while the number "60" has one significant figure. Therefore, when calculating the velocity (45/60), the answer can have only one significant figure: 0.8 km/min. However, if the time was written as "60.0" minutes, then this number would have three significant figures and the answer could have two significant figures (0.75 km/min) because the number "45" had two significant figures.
1,000 m = 1 km If there is not decimal point at the end of 1000. it is just 1km. If there is a decimal point the correct significant figures would be 1.000 km
Three.
In terms of accuracy of digits: 124 has 3 significant figures 26.3 has 3 significant figures 30 has 1 (or 2) significant figure(s)* 92.56 has 4 significant figures Thus 92.56 km is the most precise (having the most significant digits). In terms of the distance measured: 124 m is accurate to ± 50 cm 26.3 miles is accurate to (approx) ± 8047 cm 30 cm is accurate to ± 5 cm or ± 0.5 cm* 92.56 km is accurate to ± 500 cm Thus 30 cm is the most precise (having the least range of distances that round to it) * Depends if it has been rounded to the nearest 10 (30 ± 5) or 1 (30 ± 0.5)

There are two significant figures: 2 and 0 The significant figures of a number are those digits that carry meaning contributing to its precision. Leading zeros (the zero before the 2) are not significant.
