To find the fb of lead would i just do density of lead times volume of the log? I don't know how to solve for the Fb of lea what numbers to use. (11300)(0.004197531)(9.81)=465.3N
I don't have the mass of lead only the density. and how do you know its a cylinder? and if it is a cylinder i still can't find the volume that way because i don't have the radius or height.
Homework Statement
A 2.04 kg piece of wood floats on water of density 1006.2 kg/m3. If the density of wood is 486.0 kg/m3 and the density of lead is 11300 kg/m3, what minimum mass of lead, hung from it by a string, will cause it to sink?

Help please!
my questions was a little different but has the same tanks and wording, just asks stuff about different tanks.
A) The force due to the water on the bottom of tank C is... the weight of the water in the tank.
B) The water in tank C exerts an upward force on the sides of the...
