Jika di ketahui sebuah balok memiliki volume 1620 cm dan memiliki panjang:lebar:tinggi yang berbanding 5:4:3 Berapa ukuran panjang,lebar, dan tinggi balok tersebut? Tolong beri rumus nya ya!

DIK = PERKALIAN PERBANDINGAN = 5 X 4 X 3 = 60 SOL = VOLUMENYA = 1620 DIT = PANJANG = 5 LEBAR = 4 TINGGI = 3 PANJANG = DIT/DIK X SOL = 5/60 X 1620 = 135 : 9 = 15 LEBAR = DIT/DIK X SOL = 4/60 X 1620 = 108 : 9 = 12 TINGGI = DIT/DIK X SOL = 3/60 X 1620 = 81 : 9 = 9

zahraaryokoVolume = p x l x t 1620 = 5a x 4a x 3a 1620 = 60a³ a³ = 27 a = ∛27 a = 3
Maka; p = 5a = 5(3) = 15 cm l = 4a = 4(3) = 12 cm t = 3a = 3(3) = 9 cm
SOL = VOLUMENYA = 1620
DIT = PANJANG = 5
LEBAR = 4
TINGGI = 3
PANJANG = DIT/DIK X SOL = 5/60 X 1620 = 135 : 9 = 15
LEBAR = DIT/DIK X SOL = 4/60 X 1620 = 108 : 9 = 12
TINGGI = DIT/DIK X SOL = 3/60 X 1620 = 81 : 9 = 9
1620 = 5a x 4a x 3a
1620 = 60a³
a³ = 27
a = ∛27
a = 3
Maka;
p = 5a = 5(3) = 15 cm
l = 4a = 4(3) = 12 cm
t = 3a = 3(3) = 9 cm
