Hello -

I teach a remedial math class, but this question came from a man in the community that was referred to me. I figured I would try my best. I usual mess with algebra or lower math.

Here was the question:

What size rectangular tank would I need to hold about 500-600 gallons of water.
I figured the volume of one gallon is 7.48 cu ft. and V= lxwxh

Would a 4ft x4ft x 5ft be adequate?

Thank you

Cissy

Hi Cissy,

What you have done is correct but you have stated it incorrectly. One cubic foot is 7.48 gallons. Thus 600 gallons is 600/7.48 = 80 cubic feet. Hence a rectangular tank measuring 4 ft by 4 ft by 5 ft will hold 600 gallons.
