A company makes was candles shaped like rectangular prisms. Each candle is 6 cm long, 5 cm wide, and 24 cm tall. If the company used 4620 cm 3 of wax, how many candies did they make?

The volume of each candle is 6 cm * 5 cm * 24 cm = <<6*5*24=720>>720 cm^3.

Therefore, the company made 4620 cm^3 / 720 cm^3/candle = <<4620/720=6.416666666666667>>6.42 candles.
Since a candle cannot be divided, the company made 6 candles. Answer: \boxed{6}.
