Question

A student is asked to calculate the volume, in milliliters, of 2 cups of oil. there are 225mL per cup. the student calculates the volume as follows:
volume=2cups x 1cup/25mL= 8 cups
list three errors the student made

Answer 1

To calculate the volume, we use the data given above. For this problem we are asked to convert cups to mL.

volume = ( 2 cups) 225 mL / 1 cup = 450 mL

The student's error in converting is that she divide the conversion factor instead of multiplying it, wrote the conversion factor incorrectly and the units of his final answer is wrong.
