2/3 x V
= 2/3 (p x l x t)
= 2/3 (90 x 70 x 50)
=2/3 (315.000)
= 210.000 cm³
= 210 liter
Verified answer
Diketahui :p = 90 cm = 90/10 = 9 dm
l = 70 cm = 70/10 = 7 dm
t = 50 cm = 50/10 = 5 dm
Ditanya : Bnyk air mengisi 2/3 bag.bak ?
Dijawab :
Volume penuh Bak Badu
= p x l x t
= 9 x 7 x 5
= 9 x 35
= 315 cm
atau
= 315 liter
Bnyk air mengisi 2/3 bagian
= 2/3 x volume penuh
= 2/3 x 315
= 2 x 315/3
= 2 x 105
= 210 liter
Jadi, banyak air yang dibutuhkan utk mengisi 2/3 bagian bak milik Badu adalah 210 liter
