RUMUS PRAKTIS BANGUN RUANG

Rumus Volume

Volum Kubussisi x sisi x sisi
Contoh : sisi = 10 cm
Volum = 10 x 10 x 10
= 1000 cm3Rumus Luas permukaan
6 x s2
----------------------------------------------------------------------------------------------------------------------------------------Rumus balokPanjang x lebar x tinggi
Contoh : p = 6 cm
l = 5 cm
t = 4 cm
Volum = 6 x5 x 4
= 120 cm3
Rumus Luas permukaanL = 2 x (PxL + PxT + LxT)

-------------------------------------------------------------------------------------------------
Rumus prisma segitiga1/2 x panjang x lebar x tinggi

Rumus Luas permukaanL = 2 x luas alas + keliling alas x tiggi






-------------------------------------------------------------------------------------------------
Volume
V = \pi r^2 \cdot h
Rumus Luas permukaan L = 2\cdot LuasLingkaran + LuasSelimut
= 2\cdot \pi r^2 + 2 \pi r \cdot h,





-------------------------------------------------------------------------------------------------

Luas permukaan

L = \pi r^2 + \pi\cdot r\cdot s

Volume

V = \frac{1}{3}\cdot \pi r^2 \cdot t



-------------------------------------------------------------------------------------------------

Volume

V = 1/3 x Luas alas x tinggi
