well that is an easy one
Answer in feet cubed is :
X = 80 x (12/12) x (18/12)
X = 80 x 1 x 1.5
X = 120 cubic Feet
1 cubic yard = 27 Cubic F
so
Y = 120 / 27
Y = 4.44
Now typically you would order some extra to cover for spillage

How many yards of concrete do you need for my project 80 feet by 3 feet by 6 inches deep?
1.7 cubic yards of concrete Dondeb...that is an incorrect answer...Lets do this in steps.... 1. 80 X 30 = 240 Surface feet. Divide by .50 because you want it 6 inches deep. 2. 240 divided by .50 = 120 3. 120 is the total square feet of material needed. 4. Divide by 27 as there are 27 cubic feet to a cubic yard....(120 divided by 27) 5. 4.4 cubic yards of concrete are needed, that is if you don't take into account up to 10% for loss or shortage. If this were my project I would order 5 cubic yards.
How many yards of cement do you need for a 1400 x 3 slab?
The question does not provide units of measure which are important in answering the question. However, it is likely that the slab is 1400 square feet and that the slab thickness is 3 inches. A cubic yard of concrete is 3 ft by 3 ft by 3 ft, or 27 cubic feet. To solve the problem, you convert the slab size into cubic feet by multiplying the length in feet by the width in feet (to get 1400 square feet) by the thickness of the slab in inches divided by 12 inches per foot or 1400 * 3 / 12 = 350 cubic feet. To convert to cubic yards, divide the 350 cubic feet by 27 cubic ft/cubic yard to get 12.96 cubic yards. So, order 13 yards of concrete.
