21. Concrete is ordered by the cubic yard. How many whole cubic yards should be ordered for the slab in problem 20?

To determine how many whole cubic yards of concrete should be ordered, you must first calculate the total volume needed for your slab. If, for instance, your slab’s measurements yield a total volume of 2.5 cubic yards, you should round up to account for spillage and mistakes, so you’d order 3 cubic yards. It’s better to have a little extra than to run out mid-project! When ordering concrete, always remember to consider the type of project you’re undertaking. For small jobs like a backyard patio, a full truckload might not be necessary. Many suppliers will deliver smaller quantities, which is perfect for DIY projects! Always check with local suppliers for options that fit your needs.
