an air conditioning system can circulate 360, cubic feet of air per minute. how many cubic yards of air can it circulate per min

ahrayia [7]

Alright, lets get started.

3 feet = 1 yard

If we cube both sides of the equation, we will get the conversion into cubic yards

So,

$3*3*3 cubic feet = 1 * 1*1 cubic yards$

27 cubic feet = 1 cubic yards

So, 1 cubic feet = $\frac{1}{27}$ cubic yards

So, 360 cubic feet = $360 *\frac{1}{27}$ cubic yards

So, 360 cubic feet = 13.33 cubic yards

13.33 cubic yards of air can it circulate per minute. : Answer

Hope it will help :)
