A solid metal model of a rocket is made up of a cone attached to a cylinder with the same base radius. The cone has a height of 49 cm. The cylinder has a base radius of 18 cm and a height of 192 cm. Given that the mass of the model rocket is 2145 kg, find the density, in kg/m^3, of the metal which the model rocket is made of, giving your answer correct to the nearest whole number. (Density= Mass/Volume) ​
