perbandingan p:l:t suatu balok adalah 4:3:2 jika alas balok 300cm2 maka tentukan volumenya

p = 4x
l = 3x
t = 2x

luas alas = 300 cm²

luas alas = p . l
300 cm² = 4x . 3x
300 cm² = 12 x²
300 cm² / 12 = x²
x² = 25
x = 5 cm

p = 4 . 5
p = 20 cm

l = 3 . 5
l = 15 cm

t = 2 . 5
t = 10 cm

volume = p . l . t
volume = 20 cm . 15 cm . 10 cm
volume = 3000 cm³
