The pyramid P is formed from two parts made of different materials.
top
bottom
The top part of P has a mass of 92.8 g and is made from material with a density of 2.9 g/cm³
The bottom part of P has a mass of 972.8 g
The average density of P is 4.7 g/cm³
Calculate the volume of the top part of P as a percentage of the total volume of P.
