Anew sidewalk will be 4 feet wide 200 feet long and filled to a depth of 3 inches (0.25 foot) with concrete. how many cubic yards of concrete are needed?

The number of cubic yards of concrete that are needed to fill the sidewalk is 7.40741 cubic yards

where

l = length

w = width

h = height

Therefore,

l = 200 ft

w = 4 feet

h = 0.25 feet

v = 200 × 4 × 0.25

v = 200 ft³

In yards the concrete will fill the following volume:

i think is g(1)=-1.

hope that i can
