Anew sidewalk will be 6 feet wide, 240 feet long, and filled to a depth of 6 inches (0.5 foot) with concrete. how many cubic yards of concrete are needed?

6 * 240 * 0.5 = 720 feet³

720 feet³ =

26,6667 yards³ (your answer)

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
