g/mL

400

You have 2 solid cubes made of the same material.  One cube is very large and the other cube is very small.  

TRUE or FALSE: The smaller cube is more likely to float in water than the larger cube

FALSE: They're equally likely to float because the densities are the same

500

What is the upward force exerted by water that allows boats to float

buoyancy
