Tolong bantuin pakai cara perbandingan panjang lebar dan tinggi suatu balok adalah 4:3:2 jika luas alas balok itu 300 cm² maka volumenya adalah....

Diket. : p = 4 cm l = 3 cm t = 2 cm L = 300 cm2 dit. : v = ...cm3 penye. : v = p x l x t = 4 x 3 x 2 = 24 cm3

Luas alas balok = p x l 300 cm² = 4x . 3x 300 cm² = 12x² x² = x² = 25 x = √25 x = 5 p = 4 x 5 = 20 l = 3 x 5 = 15 t = 2 x 5 = 10 V = p x l x t = 20 x 15 x 10 = 3000 cm³
l = 3 cm
t = 2 cm
L = 300 cm2
dit. : v = ...cm3
penye. : v = p x l x t
= 4 x 3 x 2
= 24 cm3
300 cm² = 4x . 3x
300 cm² = 12x²
x² =
x² = 25
x = √25
x = 5
p = 4 x 5 = 20
l = 3 x 5 = 15
t = 2 x 5 = 10
V = p x l x t
= 20 x 15 x 10
= 3000 cm³
