Verified answer
4:3=10812.9=108
tingginya= 4:3:2=12:9:6
volume= 12.9.6 = 648 cm^3
■ Materi : Volume
■ Bab : Bangun Ruang
————————————————
Luas alas = p x l
108 = 4a x 3a
108 = 12a²
a² = 108/12
a² = 9
a = √9
a = 3
Panjang = 4a
= 4(3)
= 12 cm
Lebar = 3a
= 3(3)
= 9 cm
Tinggi = 2a
= 2(3)
= 6 cm
Volume balok
= p x l x t
= 12 x 9 x 6
= 648 cm³
