The amount of soil in the truckload fills a certain space, so it refers to a volume. Then, the nursery is talking about cubic yards. Make the conversion from cubic feet to cubic yards.
See solution.
Practice makes perfect
When the nursery said they will deliver a truckload with 4 yards of soil, it means 4 cubic yards. To know what to order, first find the volume of your garden, which you can do in cubic feet.
Volume of Garden: V ft^3
Next, convert from cubic feet to cubic yards by using the fact that 1 yard is 3 feet.
Volume: V ft^3 * (1 yd/3 ft)^3
⇓
Volume: V/27 yd^3
In conclusion, you must order the nursery to send V27 cubic yards of soil. Additionally, you can divide this value by 4 in order to know how many truckloads of soil to order.
