Convert the following quantities into SI units with the correct number of significant figures. (f) 2.380 mi²

Guida verificata passo dopo passo

Step 1: Identify the conversion factor from square miles to square meters. 1 square mile is equal to 2.59 x 10^6 square meters.

Step 2: Set up the conversion so that the unwanted unit will cancel out. You should multiply the given value in square miles by the conversion factor.

Step 3: Carry out the multiplication and cancel the units. This will give you the value in square meters.

Step 4: Ensure that your answer has the same number of significant figures as the original measurement. In this case, the original measurement has four significant figures, so your final answer should also have four significant figures.

Step 5: Write your final answer in scientific notation, if necessary, to reflect the correct number of significant figures.
