Answer:

800kg/m^3

Step-by-step explanation:

roh=2560/0.32m×10m/s^2

800kg/m^3

Change 32 cm to m to make it more easier.

Gravitational acceleration is 10m/s^2.

Answer:

Ro = 815.5 [kg/m³]

Step-by-step explanation:

We must use the following equation to find the hydrostatic pressure exerted on the bottom of the cylinder.


P=Ro*g*h

where:

P = pressure = 2560 [Pa]

Ro = density [kg/m³]

g = gravity acceleration = 9.81 [m/s²]

h = elevation = 32 [cm] = 0.32 [m]


2560=Ro*9.81*0.32\\Ro=815.5 [kg/m^(3) ]
