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

Length times width time the height of the room.

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