1.) Ismétlés

          Hasáb: A = 2T_a + T_p            

                      _{V =Ta ⋅ M}

     _{Téglatest: A = 2(ab + ac + bc)}

                      _{V = abc}

      _{Kocka: A = 6a²}

                  _{V = a³}

      _{Négyzetes oszlop: A = 2a²+ 4aM = 2a(a + 2M)}

                                     V = a²M

      Henger: A = 2r² 𝛑+ 2rM = 2r𝛑 (r+ M) 

                   V = r² 𝛑 M

      Gúla:  A = T_a + T_p 

                _{V = T𝚊 ⋅ M : 3}
