anonymous 4 years ago One cubic meter (1.0 m3) of aluminum has a mass of 2700 kg, and a cubic meter of iron has a mass of 7860 kg. Find the radius of a solid aluminum sphere that has the same mass as a solid iron sphere of radius 2.57 cm. Answer in units of cm

here we want to make a aluminum sphere that has the mass equal to the iron sphere here density of aluminum is is 2700kg\cubic metre so the volume of the aluminium sphere which has the mass equal to the iron will be the 7860\2700 cubic meter

$\sqrt[3]{7860\div2700}\times2.57cm=3.66 cm$
