# A cube of side length \( L \) is completely submerged in a fluid of density \( \rho \). The top of the cube is at a depth \( d \). What is the magnitude of the net force exerted by the fluid on the two vertical side faces of the cube?

A cube of side length \( L \) is completely submerged in a fluid of density \( \rho \). The top of the cube is at a depth \( d \). What is the magnitude of the net force exerted by the fluid on the two vertical side faces of the cube?

- **A.** \[ 2 \rho g L^{3} \]
- **B.** \[ \rho g L^{3} \]
- **C.** \[ \rho g d L^{2} \]
- **D.** \[ 0 \]
