| A matchbox (5cm * 3.8cm * 1.3cm) with the material of a neutron star would weigh about ten billion tons on Earth. Estimate the density of such a star
To determine the density, we will use the formula ρ = / It is necessary to find out the volume of the matchbox V = 5 · 3.8 · 1.3 = 24.7 (cm3) translate the volume into m3: 24.7 cm3 = 24.7 · 10-9m3 Determine the density ρ = 1010 ^ 9kg / 24.710-9m 3 = 0.410 ^ 18 kg / m3
