# Square feet calculations assistance

Hi all :)

Can't find an online calculator to properly do this.

I know basic sqft - if I have a room that is 12x12, the sqftg is 144. Easy.

But...

I am retiling the shower in my bathroom. Three walls, and not the ceiling nor the floor. I need to speak sqft to the tile store. Two of the walls are 58", and one wall is 36". All are 96" hi

I would like an answer, sure, but I am hoping to also learn how this is figured. Yaknow - in case this comes up again.

Thanks!

$96(2\cdot 58 + 36) = 14592 \, in^2$

$14592 \, in^2 \div 144 \, in^2/ft^2 = 101 \, \frac{1}{3} \, ft^2$

You have two 58" by 96" walls and one 36" by 98" wall. Each 58" by 96" inch wall has area (58)(96)= 5568 square inches so the two of them have area 2(5568)= 11,136 square inches. The 36" by 98" wall has area (36)(98)= 3528 square inches. That is a total of 11136+ 3528= 14664 square inches or 14664/144= 101.8 square feet. I would go up to 105 square feet to allow for errors.

(Edited thanks to skeeter.)

The 36" by 98" wall has area (36)(98)= 3528 square inches. That is a total of 10976+ 3528= 14504 square inches or 14504/144= 101 square feet. I would go up to 105 square feet to allow for errors.

36 by 98?

Hi riffwraith. Please use accurate terminology in your thread titles. The use of "ftg" is ambiguous as, as far as I know, it is not standard terminology. In fact, please try to avoid abbreviations altogether. I've edited the title for you.

Hi

Sorry, I would have thought that people as smart as the ones on this board would have known that ftg was short for footage.

Actually, I've never seen it before...and not everyone here is necessarily as "smart" as you might be assuming they are. I've edited my initial post in this thread. Please review it and post accordingly, if you will. :)

Your mistake was thinking that we were smart!
