• Kaba soo qaad Wareega Salka (P) Joogga dhinacyeda isku beegan (h) waxa uu noqonayaa bedka Dhinacyada isku beegan ee Gunbur quman sidaan ${\displaystyle {\frac {1}{2))\times P\times h}$

• Dhinacyada iska soo horjeeda = Tirada guud ee dhinacyada salka
• Tirada xarfaka ku suntan = Tirada madxaha ee salka
• Jooga Gunbur = Xariiqa lasamaynaya salka xagal Quman kuna xiran madaxa

Kaba soo qaad (p) Waa wareega salka, (h) Jooga iskasoo horjeeda ee dhinacyada, (B) Bedka salka (d) asigoo madaxa laga jaray

• Bedka Gunburka salka midka uga eg ${\displaystyle {\frac {d^{2)){h^{2))}\times B}$

Mugga Baramiid kasta cabirkiisu waa ${\displaystyle {\frac {1}{3))Bh}$ (B) Waa Bedka Salka (h) waa Jooga Gunburka
