Rumus Volume Limas terpancung - Hello greetings friends decivilisme, In the article that you will read this time with the title Rumus Volume Limas terpancung, We have prepared this article well for you to read and take learning information in it. hopefully the contents of the post what you are about to read can be understood well. happy readinga.

x/t = (b/2)/(a/2)
x/t = b/a
x = b.t/a
h = t – x
h = t – bt/a
h = t(1 – b/a)
h =t(a-b)/a
t = a.h/(a-b)
V bagian bawah = V seluruhnya – Vbagian atas
= 1/3.a2.t – 1/3 b2.x
= 1/3.a2.t – 1/3.b2.(bt/a)
= 1/3.t.(a3-b3)/a
= 1/3.(ah/(a-b)).(a3-b3)/a
= 1/3.(ah/(a-b)).((a-b).(a2+ab+b2)/a
= 1/3.h.( a2+ab+b2)
berikutnya bagai mana membuktikan x/t = (b/2)/(a/2)
Perhatikan segitiga diatas!
Dari segitiga tersebut maka berlaku :
x/t = (b/2) / (a/2).................t= tinggi segitiga keselurahan ( t = x + h)
x/t = b/a. Terbukti...
