How much mulch will you need to cover a rectangular garden that is 20 feet by 30 feet with a 3 inch layer of mulch? Explain.
V = 20 * 30 * 0.25
V = ________ cubic feet
150 feet
To calculate the amount of mulch needed to cover a rectangular garden, you need to calculate the area of the garden and then consider the desired thickness of the mulch layer.
First, find the area of the rectangular garden by multiplying its length by its width.
Area = Length x Width
Area = 20 feet x 30 feet
Area = 600 square feet
Next, determine the volume of mulch needed by multiplying the area by the desired thickness of the layer. Since the thickness is given in inches, you need to convert it to feet by dividing by 12 (since 1 foot = 12 inches).
Mulch Volume = Area x Thickness
Mulch Volume = 600 square feet x (3 inches / 12 inches/foot)
Mulch Volume = 600 square feet x 0.25 feet
Mulch Volume = 150 cubic feet
Therefore, you will need 150 cubic feet of mulch to cover a rectangular garden that is 20 feet by 30 feet with a 3-inch layer of mulch.
