Question

Calculate the Density of an steroid

An extremely massive (spherical) asteroid with a mass of 8.7 x 10¹⁵ kg passes through the atmosphere and hits the Caspian Sea. The diameter of the asteroid is determined to be 20.5 km and there are initially 78200 km³ of water in the Caspian Sea. Assuming that this asteroid is denser than water, calculate the water displacement in cubic meter. What is the density of the asteroid in g/cm³? (Hint: use the equation for the volume of a sphere)
