Question

The average density of Earth's crust 10 km beneath the continents is 2.7 g/cm^3 . The speedof longitudinal siesmic waves

The average density of Earth's crust 10 km beneath the continents is 2.7 g/cm3. The speed of longitudinal seismic waves at that depth, found by timing their arrival from distant earthquakes, is 5.4 km/s. Use this information to find the bulk modulus of Earth's crust at that depth. For comparison, the bulk modulus of steel is about 16 x 1010 Pa. Pa
