Final answer:

To determine the massiveness of a black hole that would have the same density as water, you can set up an equation using the density of water and the volume formula for a sphere.

Step-by-step explanation:

The density of water is approximately 1000 kg/m³.

To determine the massiveness of a black hole that would have the same density as water, we can set up the equation:

Density of Black Hole = Mass of Black Hole / Volume of Black Hole

Density of Water = Mass of Black Hole / Volume of Black Hole

We know the density of water and can substitute it into the equation:

1000 kg/m³ = Mass of Black Hole / Volume of Black Hole

To find the volume of a black hole, we can use the formula for the volume of a sphere:

Volume of Sphere = (4/3) * π * (radius of black hole)³

Thus, we can solve for the radius of the black hole:

1000 kg/m³ = Mass of Black Hole / ((4/3) * π * (radius of black hole)³)

Given the density of water and the volume formula for a sphere, we can calculate the massiveness of the black hole that would have the density of water.
