## Exhaust hood chu truncated pyramid ang maia siam development-pattern a ni

X - A hnuai lam base zau zawng.
Y - Pyramid atanga a san zawng.
F - Upper base sei zawng.
E - A chunglam base zau zawng.
G - Pyramid sir lam hmai sei zawng. Apofema a ni.
U - Pyramid-a inclination angle awm dan.

Online hmanga pawisa pek theih a ni.

Calculator hmang hian tetrahedral truncated pyramid, rectangular base nei parameters te chu a chhut thei a ni. Hei hi boruak luh theihna tur exhaust hood te, kitchen emaw barbecue atana hood te, chimney pipe atana hood te chhut nan a tangkai hle.

Chhiar dan hman dan tur.

Calculation siamna tur dimensions te chu thlang rawh. Pyramid dimension leh angle hriat tawhte chu pe rawh. Calculate tih kha click la. Chu chhut chhuah a nih avang chuan cap pattern drawing siam a ni.
Drawing-te hian truncated pyramid pattern atan hmun hrang hrang dimension a tarlang a.
Drawing pawh siam a ni bawk: hmalam atanga thlir leh sir lam atanga thlir.
