You need 2 3/4 wheelbarrows of sand to make 8 wheelbarrows of concrete. how much sand will you need to make 248 cubic feet of concrete

a. 84 cubic feet
b. 85 1/4 cubic feet
c. 682 cubic feet
d. not enough info

Option B.

Step-by-step explanation:

We need wheelbarrows of sand for 8 wheelbarrows of concrete.

That means ratio between sand and concrete is

Or

Now we have to calculate the amount of sand to make 248 cubic feet of concrete.

If the amount of sand required is x cubic feet then the ratio of sand and concrete will be x : 248.

Since both the ratios should be same therefore,

x =

x =

x =

  = cubic feet

Option B will be the answer.
