Given:
mass = 8000 kg
Area= 2m^2
Depth = 4m
It is a general knowledge that a density of water is 1 g/cm^3 or 997 kg/m^3, hence we can solve the given conditions by using the formula for density which is,
d = m/v
d= density
m = mass
v = volume
Solution:
In order to find the volume of the water, we multiply the area with the depth.
v = (2m^2)(4m)
v = 8m^3
Substitute the given values to the formula for density.
d = 8000 kg/8m^3
d = 1000 kg/m^3
It can be seen that the density is close to the common density of water. Therefore, we can confirm that the answer is true.
Final answer:
d = 1000 kg/m^3
