None, since there can be no conversion. A foot is a measure of length in 1-dimensional space while a square foot is a measure of area in 2-dimensional space. The two measure different characteristics and, according to the most basic principles of dimensional analysis, any attempt at comparisons or conversions between the two are fundamentally flawed.
= 40 x 80 = 3200 sq feet
8*10=80 sqf, actually...
80
80 acres = 3,484,800 square feet
44.4 square feet.
That's a total of 2560 square feet.
12 time 12 inches = 1 square foot (as there are 12 inches in a foot) 10 times 8 feet = 80 square feet 80 square feet divided by 1 square foot = 80 pavers.
8' x 10' = 80 square feet
= 40 x 80 = 3200 sq feet
A=lw A=20*80 A=1600 feet2
8 ft x 10 ft = 80 ft2 or 80 square feet.
8*10=80 sqf, actually...
80*80 = 6400 square feet
Floor and ceiling . . . (10' x 10') = 100 square feet eachFour walls . . . . . . . . (10' x 8') = 80 square feet eachTotal area inside the room = 2 (100) + 4 (80) = 520 square feet
Area of a circle in square feet = pi*radius2
Multiply the two dimensions to get the area. In this case the calculations gives you 80 square feet.
