Oh, dude, let me break it down for you. So, one board foot is equal to one square foot of lumber that's one inch thick. If you have 200 board feet, that's like having a stack of wood that's 200 square feet in area and one inch thick. So, the answer is 200 square feet. Easy peasy!
Gypsum or plaster board3 3/8 inch 1.56 pounds per square foot 1/2 inch 2.08 pounds per square foot 5/8 inch 2.60 pounds per square foot
3X.5 = 1.5 Sq Feet
1 acre = 4,840 square yards = 4,840 x 9 square feet = 43,560 square feet. 1 square foot 1 inch thick equals 1/12 of a cubic foot, so 43,560 square feet 1 inch thick equal 1/12 x 43,560= 3,630 cubic feet.
2.78 square feet.
1 yard topsoil covers 100 square feet to 3 inches, 200 square feet to 1.5 inches and 300 square feet to 1 inch.
A square foot will cover a square foot, regardless of the depth of the material the cover is made of.
