You need to order cement to make a concrete sidewalk 3 feet wide and 95 feet long. assume that the depth of the concrete is 4 inches. how much cement is needed, in cubic feet? ask your teac cement is usually ordered in cubic yards. how many cubic yards of cement do you need? (round your answer to one decimal place.)

3.5 cubic yards of cement we need.

Step-by-step explanation:

Given : You need to order cement to make a concrete sidewalk 3 feet wide and 95 feet long. Assume that the depth of the concrete is 4 inches.

To find : How much cement is needed, in cubic feet?  How many cubic yards of cement do you need?

Solution :

The length of the side walk is 95 feet long.

The width of the side walk is 3 feet long.

The depth of the concrete is 4 inches.

Convert inches into feet,

1 inch = 0.083 feet

4 inch = feet

Volume of the cement required is given by

Converting volume into yards,

Therefore, 3.5 cubic yards of cement we need.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
