Answer:
0.9 yd³
Step-by-step explanation:
Information given:
Length = 18 ft
Width = 1.5 ft
Height = 1 ft
What to find/do:
First, convert the measurement from feet to yards. (3 ft = 1 yard)
Length = 18 ft = 6 yd
Width = 1.5 ft = 0.5 yd
Height = 1 ft = 0.3 yd
Next, find the volume of the shape given. The volume would give us the amount of concrete to use in yards. 
Formula for volume = L*W*H
Plug in the values into the formula 
V = 6*0.5*0.3 = 0.9 yd³
0.9 cubic yard of concrete must be ordered to pour on the given section.
Area of the volume
