First post here so cut me some slack.

There is 43560 sqft in 1 acre not 3,560!!!

So you calculate how many sq ft (H*L) and divide by the # of sq ft in an acre.

(360*605)=217800/43560=5

The hardest part would be doing the multiplication of 360*605 without a calculator but nothing that cant be done in 1min.
