Panjang, lebar,dan tinggi sebuah balok berbanding 5:4:3.jika luas alasnya 180 cm²,maka volume balok tersebut adalah..?
5dregensleyer
Luas alas = 180 p x l = 180 5a x 4a = 180 20a² = 180 a² = 180/20 a² = 9 a = 3 volum = p x l x t = 5(3) x 4(3) x 3(3) = 15 x 12 x 9 = 1620 cm³
jawabnnya D

ha tapi disini obsennyA:A.216. B.540 C.1080 D. 1620
p x l = 180
5a x 4a = 180
20a² = 180
a² = 180/20
a² = 9
a = 3
volum = p x l x t
= 5(3) x 4(3) x 3(3)
= 15 x 12 x 9
= 1620 cm³
jawabnnya D
5a x 4a = 180
20 a kuadrat = 180
a kuadrat = 9
a. = 3
kemudian mencari sisi" nya
p = 5.a = 5.3 = 15
l = 4.a = 4.3 = 12
t = 3.a = 3.3 = 9
volume = p x l x t
= 15 x 12 x 9
= 1620 cm kubik
