In order to find the volume of the wooden block, Dash and Bob would use the formula:
Length x Width x Height = Volume of a Rectangular Prism (in cubic units)
3.10 cm x 0.50 cm x 2.0 cm = 3.1 cubic centimeters
The volume of the wooden block is 3.1 cubic centimeters
Rules for finding the number of significant figure include:
- The leftmost digit which is not a zero is the most significant number.
- If the number does not have a decimal point, the rightmost digit that is not a zero is the least most significant number.
- If the number does have a decimal point, the rightmost digit is the least significant, even if it is a zero.
- Every digit between the least and most significant digits should be counted as a significant digits.
The number of significant digits in a product (multiplication) or quotient (division) is the same number of significant digits as in the number with the lowest number of significant figures.
