Can you help me with this question?

Problem 3: Floating block You place a rectangular solid block in a tub containing water (Pwater = 1 g/cm). The air above the water surface is at atmospheric pressure (Patm = 101325 Pa). The height of the block as shown in the figure (hblock) is 10 cm and its widths in the other two directions (Wblock) are equal, 20 cm. The block has a mass (mblock) of 2800 g. Wo air Patm block hblock h1 water A) Develop a formula in terms of the given variables (Patm, Pwater, holock, Whlock, Mblock) that describes the height of the submerged portion of the block, hs. B) Calculate h, in units of cm. Now, assume that you know that the material the block is made of has a contact angle of water on its surface equal to 30. (Remember, the surface tension of water is 72.8 dynes/cm). C) If you accounted for these surface tension effects, would the block be submerged farther into the water, less submerged in the water, or submerged by the same amount regardless of surface tension and contact angle.
