Answer:
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.
