Question

The weight of a brick in air is W_{in air} = 23 lb, while the weight of the same brick when it is completely submerged in water (ρ_water = 1.0 g/cm³) is W_{in water} = 19.3 lb (it is called apparent weight). What is the density of the brick?

The density of the brick, ρ_brick =

What are the mass and volume of the brick?

The mass of the brick, M_brick =  

The volume of the brick, V_brick =

What is the apparent weight of the same brick if 60% of it is submerged into a fluid with 1.54 g/cm³ density and the rest of the brick is in air?

The apparent weight of the brick, W_{in fluid} =
