a sidewalk is 5ft wide, 6in deep, and 220 ft long. how many cubic yards of concrete are needed to fill it?
tangare [24]

Answer:

1100/54 yds

Step-by-step explanation:

First convert inches and feet to yards

[3 ft = 1 yd, 12in = 1yd]

5ft = 1 2/3 yds

6in = 1/6 yds

220ft = 73 1/3 yds

Now use the volume formula,

b*w*h = A

[1 2/3] * [1/6] * [73 1/3]

= [5/3] * [1/6] * [220/3]

= [5/18] * [220/3]

= 1100/54 yds
