How does a star with ten times the mass of the Sun consume its hydrogen fuel reservoir?

At a vastly accelerated rate due to higher luminosity

Although a star possessing ten times the mass of the Sun naturally starts with ten times the amount of available hydrogen fuel in its core, its energy consumption rate is not proportional to its fuel supply increase. Due to the overwhelming gravitational compression associated with that high mass, the core temperature required to maintain balance demands a significantly higher energy output, resulting in a luminosity that is thousands of times greater than the Sun's. This translates directly into a consumption rate for hydrogen fusion that is staggeringly fast. Consequently, despite having more fuel, the more massive star exhausts its reservoir rapidly, leading to a much shorter main-sequence tenure compared to less massive stars.
