Answer:
cubic feet of concrete mix needed for the patio is:
180 cubic feet
Step-by-step explanation:
We are given that:
James wants to pour a patio that is 18 feet by 20 feet. He wants the concrete to be 6 inches deep.
The patio is in the shape of cuboid with
Length(l)=18 feet
Breath(b)=20 feet
Height(h)=6 inches=0.5 feet (since, 1 feet=12 inches)
Concrete required=volume of that patio=lbh
=18×20×0.5
= 180 cubic feet
