someone told me that the square ft of a 14x20 room was 820 sq ft could someone please tell me in detail how they figured this thanks

Take 14 and times it by 20 = 280 sq ft. I don't know where they get the 820 sq ft. unless then transposed the 2 and the 8 in the number.

Yes, for square feet, you merely multipy the length of the room times the width..

I don't know where the 820 came from that is not correct

Depends what they were calculating for. If they were calculating for paint coverage with an 8 foot ceiling:

Wall 1: 14' x 8' = 112 Sq.Ft.
Wall 2: 20' x 8' = 160 Sq. Ft
Wall 3: 14' x 8' = 112 Sq.Ft.
Wall 4: 20' x 8' = 160 Sq. Ft.
Ceiling: 14' x 20' = 280 Sq.Ft.

Total is 824 Sq.Ft. - close enough for government work?

Everything's a matter of perspective.

OK if 280 is the sq ft of a 14x20 room what is the area sq ft of the room if that makes sense

<moved from Other Careers to Construction>

OK do you want the cubic square feet of the room,

Length times width time the height of the room.

What is square footage of 8ftx18ftx9ft

That is volume, cubic feet, not square feet. 2 factors for square, 3 for volume. What are you trying to figure out?
