Dik: V = 3.600 dm3 = 3.600.000 cm3 a = 24 cm t = 10 cm Dit: T? Jawab: V= 1/2 x a x t T 3.600.000 = 1/2 x 24 x 10 x T 3.600.000 x 2 / 24 x 10 = T 30.000 cm = T

Jawabannya L a x t = 3600 1/2 x a x t(segi tiga) x t = 3600 1/2 x 24 x 10 x t = 3600 120 x t = 3600 t = 3600/120 t = 30
Dit: T?
Jawab:
V= 1/2 x a x t T
3.600.000 = 1/2 x 24 x 10 x T
3.600.000 x 2 / 24 x 10 = T
30.000 cm = T
L a x t = 3600
1/2 x a x t(segi tiga) x t = 3600
1/2 x 24 x 10 x t = 3600
120 x t = 3600
t = 3600/120
t = 30
