Suppose you arrive at a planet with the same mass per unit volume as the Earth but has 31 times Earth's radius. ?
What would you weigh on this planet compared with what you weigh on Earth?

ge = ρ*r^3/r^2 = ρ*r
gp = ρ*31^3*r^3/(31^2*r^2) = ρ*31*r
gp/ge = ρ*31*r / (ρ*r) = 31
gravity on planet gp = 31 times gravity ge on Earth
