The last significant figure of a number may be underlined; for example, “2000” has two significant figures. A decimal point may be placed after the number.
How many significant figures is 1000?
so 1000. is our four-significant-figure answer. (from rules 5 and 6, we see that in order for the trailing zeros to “count” as significant, they must be followed by a decimal. Writing just “1000” would give us only one significant figure.)
How many significant figures does 3000 have?

How do you calculate volume?
- Volume = length x width x height.
- You only need to know one side to figure out the volume of a cube.
- The units of measure for volume are cubic units.
- Volume is in three-dimensions.
- You can multiply the sides in any order.
- Which side you call length, width, or height doesn’t matter.
How do you multiply sig figs?
When multiplying two numbers, the important value is the number of significant figures. If the numbers being multiplied have three significant figures, then the product will have three significant figures. For example, if you wanted to find the area of a rectangular yard, you would measure the length and width.
How do you add and subtract sig figs?
When you add or subtract, you assign significant figures in the answer based on the number of decimal places in each original measurement. When you multiply or divide, you assign significant figures in the answer based on the smallest number of significant figures from your original set of measurements.
