Problem 1: Calculate how high the continental crust will 'float' above the mantle (in km) if it's average thickness is 30 km, the density of the continental crust is 2.7 g/cm3, the density of the oceanic crust is 2.9 g/cm, and the density of the mantle is 3.3 g/cm. (Give your answer in km and report your answer to 2 decimal points)
Problem 2: Calculate how high the oceanic crust will 'float' above the mantle (in km) if its average thickness is 10 km, the density of the continental crust is 2.7 g/cm3, the density of the oceanic crust is 2.9 g/cm, and the density of the mantle is 3.3 g/cm'. (submit your answer to 2 decimal places)
