Your garden is to be rectangular shaped and surrounded by a fence of 300 feet you need to buy soil at 3.50 per yard calculate the volume of the soil in the garden given the soil must be 6 inches deep?

Answer 1

300 sq ft = 43,200 sq in [1 sq ft = 144 sq in]. 43,200 sq in x 6 in = 259,200 cu in of soil volume. The above assumes the garden is 300 sq-ft, but the question actually says 300 ft of fence length, not garden area. You would have alot of spare fence if your garden was only 300 sq-ft. So lets assume a rectangle with the dimensions of 100 ft x 50 ft (300 feet fence total legth), which gives an area of 5000 sq-ft. With the soil being 1/2 foot deep, the volume is calculated as 5000 sq-ft x 0.5 ft = 2500 cu-ft (or 92.6 cu-yards: 1 cu-yd = 27 cu-ft). However, as the dimensions of the rectangle change, so will the area, and so will the volume.
