Question

Please help! Use 4 unit multiplers to convert 625 square yards to square inches.

Answer 1

So I think this is just a dimensional analysis question if I understand what you mean by "unit multipliers".

You start with 625 yards, and you want to get to inches.
Going from yards to inches means we want to go smaller.

Try going from yards-> feet -> inches. I can't imagine you would need an extra unit multiplier. It's feasible in 3.
