What is the meter?
The formula for calculating buoyant force acting on an object.
What is density of the fluid x volume displaced x gravitational acceleration?
You have a boat with a hull volume of 4.5 cubic meters that is floating in a lake. Calculate the buoyant force acting on the boat. Assume the density of water in the lake is approximately 1000 kg/m³, and the gravitational acceleration is approximately 9.81 m/s².
What is 1000 kg/m3 x 4.5 m3 x 9.81 m/s2 = 44145 N?
