You're pouring a patio.
10 by 12, 4 inches deep. That's not 480 cubic feet.It's 1.48 cubic yards. The supply house sells concrete by the yard, not the foot. And rounding wrong here means a second trip when the truck driver tells you to come back tomorrow.
Journeyman does the math the way a concrete guy would — in the units the supply house actually uses. Ask “how many yards of concrete for a 10 by 12 patio, 4 inches deep” and you get 1.48 yd³. Round up to 1.5 to be safe. Done.
What it's like to actually use this
You measured the walls. You know you need drywall. Then there's compound. And tape. And screws. And corner bead.
