Bab Bangun RuangMatematika SMP Kelas VIII
Kubus
Volume = 125
s³ = 125
s = ∛125
s = 5 cm
s = d = 5 cm
r = d/2
= 5/2
= 2,5 cm
Bola
Volume = (4/3) . π . r . r . r
= (4/3) . 3,14 . 2,5 . 2,5 . 2,5
= 65,1467 cm³

Bangun Ruang Sisi Lengkung.Panjang rusuk kubus sama dengan diameter bola. s = d
V kubus = s³
s = ∛(V kubus)
= ∛(125 cm³) = 5 cm
V bola = 1/6 πd³
= 1/6 (3,14)(5 cm)³
≈ 65,4167 cm³
