IF the lawn is rectangular, then the area is (395 x 236) = 93,220 square feet, or about 0.47 acre.
60 pounds of fertilizer, spread over the 12,000 square foot lawn, an acre is 43,560 square feet or 220 lbs +/-.
1 acre = 43,560 sq ft. The lawn is 12,277.8 sq ft, = 0.28 acre
Well, it depends on what you mean. One acre is the same as 43,560 square feet. (And it doesn't matter the shape, but a "square acre" would be about 208 feet on a side.) So, there's plenty of room for a nice big ranch style house of even 2,300 square feet with a big lawn to mow. If you wanted a house that has 1 acre of floor space, that's a lot of bathrooms and bedrooms! FYI, Buckingham Palace is 828,818 square feet, or about 19 acres. So, the final answer is"yes, you can build a home on one acre."
it's 14x24, which is 336 square feet
If the dimensions are in feet then 10 times 30 = 300 square feet
28 feet long and wide
70 feet x 45 feet = 3150 square feet.
18 and 8
70 x 70 = 4,900 square feet
50 x 70 = 3,500 square feet
1 acre = 43560 square feet. 4 acres = 174240 square feet According to the label, it's 5 pounds (1 box) per 4000 square feet. 174240 / 4000 = 43.56 boxes 43.56 x 5 = 217.8 pounds.
