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
<u>First Candle</u>
Height=12cm
Length=4 cm
Width= 6 cm
Volume=Height X Length X Width
=12 X 4 X 6
=288
<u>Second Candle</u>
The second candle is 4cm higher
Height=12+4=16cm
Length=4 cm
Width= 6 cm
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.
