Ronin Payne · Answer 1

5100 cm of wax will make 17 candles

Step-by-step explanation:

Each candle is 5 cm long, 4 cm wide, and 15 cm tall

to know the space they cover, we divide it with their volume and since they are in rectangular prism

Volume is length x width x height

5 x 4 x 15 = 20 x 15 = 300cm

1 candle = 300cm

what number of candle is represented as x

1 candle comprises of 300cm wax

x = 5100

300x = 5100 x 1 = 5100

300x = 5100

x = 5100/300 = 17

5100 cm of wax will make 17 candles
