Abuilding has a concrete foundation that's 24" wide and 36" deep at all points. how many cubic yards of concrete are necessary to pour the foundation for the back wall which is 30' in length?

a. 60 cubic yards
b. 6.66 cubic yards
c. 960 cubic yards
d. 24.88 cubic yards

1 yard = 3 feet

The foundation is 2/3 yard wide, by 1 yard deep by 10 yards long.

Volume is Length x width x height.

Volume = 2/3 x 1 x 10 = 6.66 cubic yards.

The answer is B.

no

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
