Question
A block of wood with length "h" and cross-sectional area "A" is submerged in water with 50 mm exposed
above the water surface. When submerged in a liquid with a specific gravity of 1.35, it will float with 75
mm exposed above the liquid surface.
3. Obtain the specific gravity of the wood.
a. 0.659
b. 0.524
4. Obtain the length of the wood.
a. 163.2
b. 124.8
c. 0.956
c. 132.1
d. 0.752
c. 10.50 m²
d. 146.4
5. A block of wood is 20 mm thick is floating in seawater. The specific gravity of wood is 0.65 while that
of seawater is 1.03. Find the area of a block of wood, which will just support a man weighing 80 kg when
the top surface is just at the water surface.
a. 13.73 m²
b. 14.43 m²
d. 9.36 m²
