How many gallons of water can be collected in all the rain barrels used by Sunny Days Greenhouses for their two largest greenhouses?

Back

6,764.31 gallons

Answer explanation

Diameter = 4 ft, Height = 6 ft, and Radius = 2 ft

V = חr²h

V = 3.14(2²) (6)

V = 3.14 (4) (6)

V = 75.36 Ft³

7.48 X 75.3 = 563.69 gallons

563.69 gallons X 12 (6 per greenhouse x 2 greenhouses) = 6,764.31 gallons

You are ordering potting soil for your greenhouse’s spring crops. You need enough potting soil to fill the following number of containers: 35 (8” baskets with saucers), 75 (10” baskets with saucers), 250 (4” square pots), 425 (6” azalea pots), 120 (8” standard pots). How many bags of potting soil must be ordered?

Back

23 bags

Answer explanation

35 8” baskets with saucers / 26 = 1.35 bags

75 10” baskets with saucers / 14 = 5.35 bags

250 4” square pots / 130 = 1.92 bags

425 6” azalea pots / 53 = 8.02 bags

120 8” standard pots / 20 = 6 bags

1.35 + 5.35 + 1.92 + 8.02 + 6 = 22.64 or 23 bags
