The sound box of a guitar gives more surface area to produce sound.
Explanation:
A guitar string vibrating by itself doesn't produce very much sound. This is because a guitar string has a very small surface area and therefore cannot compress very much air. Remember that sound is a compression wave in air. The guitar is constructed in such a way that the vibration of the strings gets transferred to the wooden sound box. Because of the large surface area of the sound box it is able to compress much more air and produces a much louder sound than the string on its own.
