Just about 400
400 square feet
I'm going to say 400.
400 square meters are 4.3 thousand square feet.
Divide pounds by 14 to get stones: 400/14= 28.6(28.57142857142857) stone.
400 square feet (20 x 20 = 400)
400 sq cm equals 0.43 square feet.
400 square feet = 44.4 square yards.
There are 256,000 acres in 400 square miles. This is calculated by multiplying the number of square miles by 640 (which is the number of acres in a square mile).
25 x 16 = 400 square feet.
400 square feet = 37.16 square meters.
