Q
formula for density
A
ρ=m/V
ρ means density (g/cm^3)
m means mass (g)
V means volume (cm^3)
2
Q
pressure formula
A
p=F/A
p means pressure (Pa, Pascals)
F means force (N)
A meant area (m^2)

Q
method to measure volume
A
- to measure the volume, use a eureka can and fill it with the maximum amount of water that it allows.
- put a measuring cylinder under the spout
- carefully, place the statue in the can
- measure the displaced water that comes out of the spout and into the cylinder
- find the mass of the statue by placing it on a balance and recording the mass.
- to find the density of the statue, divide the mass by the volume of displaced water.
