Solution: The capsule consists of a cylinder of height $10 - 2 \times 2 = 6$ units (subtracting the hemispheres) and two hemispheres (equivalent to one sphere). Volume of the cylinder: $\pi r^2 h = \pi \times 2^2 \times 6 = 24\pi$. Volume of the sphere: $\frac43\pi r^3 = \frac43\pi \times 8 = \frac323\pi$. Total volume: $24\pi + \frac323\pi = \frac1043\pi$. \boxed\dfrac1043\pi - Abu Waleed Tea
