How many cubic feet are in 3 cubic yards? a. 5,184 cu. ft. b. 9 cu. ft. c. 27 cu. ft. d. 81 cu. ft.

D. 81 cu. ft.

Step-by-step explanation:

One yard has 3 feet.

A cubic yard means three dimensions, length, width, and height, all of which will have 3 feet.

In order to get the amount of cubic feet in one cubic yard we just need to multiply the three sides:

3 x 3 x 3 = 27

So one cubic yard has 27 cubic feet.

Now we just need to multiply this number with the number of cubic yards, which is 3:

27 x 3 = 81

So we have a result of 81, meaning there are 81 cubic feet in 3 cubic yards.

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
