6 inches turned into feet in 0.5, to find the answer you need to do 18*20*0.05 and you will get 180, 180 is your answer (:

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
