I am trying to solve a formula but i am completely stuck
The formula is zc.ρc = zw.ρw + zo.ρo + [zc-(zh + zw + zo)].ρm
Where ZH is height of himalaya, ZW is water depth, ZO is ocean crust And P is density (po=density of ocean crust etc)
The known numbers are(in km) ZH = 8, ZW = 5 and ZO = 7 i
And the mass is based on 1m2 (plus height of various variables)
