Answer: It will take about 12.75 pounds of grass seed, if the square footage amounts in the question are correct,
Step-by-step explanation: To get unit rate, ft²/lb, divide
80/3 = 26.667 square feet per pound
divide 340 by 26.667 = 12.749 Round to12.75 pounds required.
*These numbers are nowhere near real life amounts. 3 pounds of grass seed is normally enough for 800 to 1000 square feet.
