Complete each calculation and determine the answer using the correct number of significant figures. 3.214mm times 1.5mm vmm^2 4.8 +5L=square L 4.82 4821

## Step 1:<br />The first calculation is a multiplication of two measurements in millimeters. The rule for multiplication and division in significant figures is that the result should have the same number of significant figures as the original number with the fewest significant figures. In this case, 1.5mm has two significant figures, so the result should also have two significant figures.<br /><br />## Step 2:<br />The second calculation is an addition of two measurements in liters. The rule for addition and subtraction in significant figures is that the result should retain the same number of decimal places as the original number with the fewest decimal places. In this case, 5L has no decimal places, so the result should also have no decimal places.
