perbandingan panjang, lebar, dan tinggi balok 4 : 3 : 2. jika luas alasnya 768cm², hitunglah volumenya

Luas alas = pl
768 = 4x . 3x
768 = 12x²
x² = 768/12
x² = 64
x = √64
x = 8 

t = 2(8) = 16 cm;

maka;
volume
= Luas alas . tinggi
= 768 . 16
= 12288 cm³

Luas alas PL
768cm² = 4x · 3x
768cm² = 12x²
64cm² = x²
8cm = x

Panjang
= 4 x 8cm
= 32cm

Lebar
= 3 x 8cm
= 24 cm

Tinggi
= 2 x 8cm
= 16cm

Volume
= P x L x T
= 32cm x 24cm x 16cm
= 12.288cm³
