Sebuah balok memiliki luas sisi masing-masing 30 cm^2 18 cm^2 dan 15 cm^2 tentukan volume balok tersebut!

V = p x l x t
= 30 x 18 x 15
= 8100
= √8100
= 90 Cm^3

p x l = 30 cm²
l x t = 18 cm²
t x p = 15 cm²

l = 30/p
t = 15/p

30/p x 15/p = 18
450/p² = 18
18p² = 450
p² = 450/18
p² = 25
p = √25 = 5 cm

p x l = 30 cm
5 x l = 30 cm
l = 30/5 = 6 cm

t x p = 15
t x 5 = 15
t = 15/5
t = 3 cm

Vol = p x l x t
Vol = 5 x 6 x 3
Vol = 90 cm³
