L = p x l
300  x = 4 x 3
300 x = 12
x = 300/12 = 25

P = 4/25 x 300 = 48
L = 3/25 x 300 = 36
T = 2/25 x 300 = 28

V = P x L x T
=48 x 36 x 28 = 41472

Coba dicek,maaf kalau salah..!

p  :  l  :  t
4  : 3  : 2

Luas alas = P x L
300 = 4 x 3
300 = 12
 \frac{300}{12}  =  X^{2}
25 =  X^{2}
5 = x

Volume = P x L x T
= 4(5) x 3(5)x 2(5)
= 20 x 15 x 10
= 3000
