57.0 is it rounded to three sig figs. You count three spaces then round from there, which would be the zero and you would round down because the four is there.

Since the Summer solstice is when the sun is highest in the sky and the solstice is in June, that's your answer :)
Density equals mas divided by volume. You know the density and mass so use it to solve for the volume.
d= m/v
d= 19.3 g/mL
m= 50g
v=?
Plug it in. 19.3= 50/v
To solve for v you do the opposite of 50 divided by v which is 50 time v.
That cancels v from the right side of the equation. Do the same on the other side(times v)
19.3 * v=50
Now just divide both sides by 19.3 to get v alone.
