Question

a company makes wax candles shaped like rectangular prisms. each candle is 5 cm long, 4 cm wide, and 12 cm tall. if the company used 3,840 \\(\mathrm{cm}^3\\) of wax, how many candles did they make? \\(\square\\) candles

Explanation:

Step1: Calculate volume of 1 candle

Volume of a rectangular prism is $V = l \times w \times h$, so:
$V = 5 \times 4 \times 12$
$V = 240$ $\text{cm}^3$

Step2: Divide total wax by 1 candle volume

Number of candles = $\frac{\text{Total wax volume}}{\text{Volume of 1 candle}}$
$\text{Number of candles} = \frac{3840}{240}$

Answer:

16 candles
