A wooden block of mass 12 kg is floating in a pool. This is a fresh water pool, so we can assume a density of 1000kg/m³, What is the volume of water displaced by this wooden block? m3 Submit Answer Tries 0/2 If the volume of the block is 64 liters, what is the density of the block in kilograms per liter? kg/L Submit Answer Tries 0/2 What is the density of the block in kilograms per cubic meter? kg/m3 Submit Answer Tries 0/2 What percentage of the block is submerged?

A very simple way of measuring the depth of a fluid in a gas station's underground gasoline tank is by using a pressure gauge that measures gauge pressure. Assume the fluid in the tank is gasoline with a density of 700 kg/m3 and g = 9.80 m/s2. If the gauge pressure is 25.9 kPa what is the depth of the gasoline in the tank? Assume 3 significant digits. Watch the units!   A. 3.78 cm   B. 37.8 m   C. 0.378 m   D. 3.78 m   E. 3.78 mm
