Explanation:

Density is mass divided by volume.  For example, Block A:

ρ = m / V

ρ = 60 g / 125 cm³

ρ = 0.48 g/cm³

I assume each block is a cube, so the length of block underwater divided by the side length of the block is the percent underwater.

% = 1.8 / 3.9

% = 46%

Repeat for Blocks B through E.
