3. A wooden body with relative density of 0.57 floats a liquid with unknown relative density. If the volume of the wooden body above the liquid surface is 25 percent of the total volume of the body, what is the relative density of the liquid? 4. A batch of concrete consisted of 200 lbs fine aggregate (sand), 400 lbs coarse aggregate (gravel), 95 lbs cement, and 5 gallons of water. The relative density of the sand and gravel may be taken as 0.65 and that the cement as 3.10 What was the total volume of concrete produced?
