Anew sidewalk will be 5 feet wide, 240 feet long, and filled to a depth of 9 inches (0.75) with concrete. how many cubic yards of concrete are needed?

In order to build the sidewalk, they would need around 33  yrds^3 of concrete. This is because the problem is asking for the volume of the sidewalk. First, we need to convert everything into yards. The final answers we would get would be (5/3) (80) and (0.25). If we were to use the formula for volume, it would be V=lwh. With that incorporated, the answer would be 33.3333333 yrds^3 of concrete to be exact.

if you use photomath right away it will give you the answer not like this app that you have to wait for people.
