Eddie and the Flower garden

Question

Eddie and his dad are putting in a garden for Eddie's mom as her Mother's Day present. They will need to add a 3 inch layer of compost to mix in the soil in order to make a fertile bedding for the plants.One bag of compost will cover an area of 20 square feet and 3 inches thick. The garden plot measures 11 by 14 feet. Estimate the number of bags of compost Eddie and his dad will need ?

Answer 1

Area of garden = (14 ft)(11 ft) = 154 ft²

Number of bags = (154 ft²)(1 bag / 20 ft²) = 7.7 bags

Since you can't buy 0.7 bags, they need 8 bags to do the job.
