Question

How many candles did the company make if they used 3840 cm³ of wax for each candle, and each candle is a rectangular prism measuring 5 cm in length, 4 cm in width, and 12 cm in height?

A) 12 candles
B) 20 candles
C) 24 candles
D) 32 candles

Answer 1

The company made 32 candles.

Step-by-step explanation:

To calculate the volume of the candle, we need to multiply the length, width, and height. The volume of a rectangular prism is given by the formula V = l x w x h. Therefore, the volume of each candle is 5 cm x 4 cm x 12 cm = 240 cm³. To find the number of candles, we can divide the total volume of wax used (3840 cm³) by the volume of each candle (240 cm³). 3840 cm³ / 240 cm³ = 16 candles. Therefore, the correct answer is D) 32 candles.
