Diketahui jumlah panjang rusuk balok 144 cm. jika perbandingan panjang, lebar, dan tinggi balok = 5:4:3, hitunglah:
a. panjang, lebar, dan tinggi b. volume

2( 5a + 4a + 3a ) = 144 2 ( 12a ) = 144 24a = 144 a = 6 jawabn a.) panjang = 5a = 5 x 6 = 30 lebar = 4a = 4 x 6 = 24 tinggi = 3a = 3 x 6 = 18 b.) volum = 18 x 24 x 30 = 12.960

a.) panjang = 5a

lebar = 4a

tinggi = 3a

b.) volum = 18 x 24 x 30

PERBANDINGAN PANJANG= 5=>DIT
PERBANDINGAN LEBAR = 4=>DIT
PERBANDINGAN TINGGI = 3=>DIT
JUMLAH PERBANDINGAN = 5 + 4 + 3 = 12=>DIK
JUMLAH PANJANG RUSUK = 144 CM =>SOL
PANJANG = 5/12 X 144 = 60 CM
LEBAR = 4/12 X 144 = 48 CM
TINGGI = 3/12 X 144 = 36 CM
