Best answer
  • Formula of calcium hydroxide is Ca(OH)2
  • From criss-cross method we know that the valency of calcium is 2 i.e., Ca+2 and hydroxide is 1 i.e., OH- .
  •  Formula of zinc phosphate is Zn3(PO4)2
  • Valency of Zn is 2 i.e., Zn+2 and valency of phosphate is 3 i.e., P\(O_4^{-3}\) . 
  • Now the formula of calcium phosphate according to criss-cross method is Ca3(PO4).
