7.2*12*0.23 = 19.872
To round to the nearest hundredth look at the '7' because it is in the hundredths column.
Now look at the number AFTER 7, it is a 2 which means you would leave it the same.
Which means your answer would be:
A. 19.87
But IF the number after 7 was, let's say 5, you would round it up so the number would become 19.88
