# A cube of side length \( s \) rests on the bottom surface of a container of fluid as shown in the figure. The fluid is at a height \( y \) above the bottom of the tank. The fluid has density \( \rho \) and the atmospheric pressure is \( P_{\text{atm}} \).Which of the following expressions is equal to the absolute pressure exerted by the fluid on the top surface of the cube?

A cube of side length \( s \) rests on the bottom surface of a container of fluid. The fluid is at a height \( y \) above the bottom of the tank. The fluid has density \( \rho \) and the atmospheric pressure is \( P_{\text{atm}} \).

Which of the following expressions is equal to the absolute pressure exerted by the fluid on the top surface of the cube?

- **A.** \[ P_{\text{atm}} + \rho g y \]
- **B.** \[ P_{\text{atm}} + \rho g (y – s) \]
- **C.** \[ \rho g y \]
- **D.** \[ \rho g (y – s) \]
