Use three unit multipliers to convert 4700 cubic feet to cubic yards.
:
4700%28ft%29%5E3+%281%2F3%29%28yd%2Fft%29=1566.67%28ft%5E2%28yd%29%29%281%2F3%29%28yd%2Fft%29=522.22+%28ft%28yd%29%5E2%29%281%2F3%29%28yd%2Fft%29=+174.07+%28yd%29%5E3
:
the multiplier was the same throughout in this instance. the just want you to see the steps of how it gets from ft%5E3 to yd%5E3
:
a short cut would be to know that there is 27 cubic feet in 1 cubic yard
:
4700/27=174.07
:
but again they want the kids to see the steps. and how the the units interact with each other

I think that they want you to use 3ft/yd three times (for cubed)

actually, if they want a "multiplier"; it would be (1/3)yd/ft


4700 ft^3 * (1/3)yd/ft * (1/3)yd/ft * (1/3)yd/ft = 522 2/9 yd^3
