In order to understand this concept, we first must understand standing waves and resonance.
A standing wave is a superposition of two waves with equal amplitude and frequency who are travelling in opposite directions.
Because of different superpositions along the line, standing waves do not transmit energy through space.
When an objects starts resonating with an external frequency which is near its natural frequency, the object will start to rapidly gain energy (and the amplitude of oscillations will increase dramatically). This efect is known as resonance.
In a guita, strings will start to oscillate due to external forces and standing waves will form. Sound produced from those strings will enter the hollow part of the guitar and amplify itself through the effect of resonance. That is how a guitar can produce a very loud sound.
