How many yards is 15 cu feet?

Answer 1

Mathematically, a yard is a measure of length, has only one dimension and thus has no volume which has three dimensions; so no matter how many of them you have you will never get a volume of 15 cu ft.

If you are using "yard" in the slang, builders' way to represent cubic yards, then:

1 yd = 3 ft

1 cu yd = 1 yd x 1 yd x 1 yd

= 3 ft x 3 ft x 3 ft

= 27 cu ft

⇒ 15 cu ft = 15 ÷ 27 cu yd

= 5/9 cu yd

≈ 0.56 cu yd
