A room is 12x20 feet with a 10 foot ceiling. A gallon of paint covers 350 square feet. How many gallons do I need to complete the job?

I'm hiring a crew for a temporary job. Should I hire 10 less experienced people at $12/hr or should I hire 8 more experienced people who are 20% more productive at $15/hr?

My work truck gets 20 mpg. Along with insurance and depreciation, how much should I charge per mile for work related travel? How much should I charge if the price of fuel increases by 3%?

I could go on...

I got a 20 amp recept circuit to trouble shoot...should I use a voltmeter or ohms law?

Figuring square feet is not algebra...it’s simple math.
L X W X H

Configuring the formula used to find the answer on the opposite of the equals symbol is algebra.

L X x X H = sq ft.
