John made two candles in the shape of rectangular prisms. The first candle is 12cm high, 4 cm long, and 6 cm wide. The second candle is 4 cm higher, but has the same length and width. How much additional wax was needed to make the taller candle?

96

Step-by-step explanation:

To determine how much additional wax was needed to make the taller candle, we determine the volume of each of the candles and find the difference in their volumes

First Candle

Volume=Height X Length X Width

=12 X 4 X 6

=288

Second Candle

The second candle is 4cm higher

Volume=Height X Length X Width

=16 X 4 X 6

=384

Difference in Volume = 384-288 =96

Therefore, 96 of additional wax was used to make the second candle.
