Uma uzonamathisela izindonga, unamathisele iphepha lokunamathisela odongeni, noma amathayela, udinga ukubala inani lempahla edingekayo ukuze kulungiswe. Ngemuva kokubala indawo yezindonga ezingama-XNUMX, udinga ukususa kuzo ubukhulu bomnyango newindi. Lokhu kuzokusiza ukuthi ungakhokhi kakhulu izinto zokwakha. Isibali sizokusiza ukubala ngokunembile indawo yomnyango wama-XNUMX.
Ukuze ubale indawo yomnyango, udinga ukuphindaphinda ukuphakama kwawo ngobubanzi. I-tape measure isetshenziselwa izilinganiso, futhi idatha etholiwe isetshenziswa ngamasentimitha noma iguqulelwe kumamitha.
Ifomula yokubala indawo yomnyango yobukhulu ngamamitha:
S=h*a
Ukuze uthole izibalo ngamasentimitha:
S=h*а/10000
kuphi:
- S - indawo yomnyango;
- b - ububanzi;
- h – ukuphakama.
Njengomphumela, sithola indawo engu-uXNUMXbuXNUMXb umnyango noma ukuvulwa ngamamitha-skwele - м2.
Isibali esiku-inthanethi sizokwenzela izibalo ngokushesha futhi ngaphandle kwamaphutha. Kuyadingeka ukulinganisa ngamasentimitha engxenyeni engaphandle yohlaka lomnyango noma izandiso.
Uma ku-calculator kanye nomnyango singena izilinganiso zefasitela, sizothola indawo yabo ephelele. Lapho kulungiswa igumbi, lo sayizi kufanele ususwe endaweni ephelele yezindonga ezingama-uXNUMXbuXNUMXb ukuze ungathengi impahla eyeqile. Ukuze ubale, linganisa ifreyimu yewindi noma iwindi elivuleka ngamasentimitha, bese ulufaka ezinkambeni zokuvulwa kwesibili kwesibali.
