tolong di jawababya pleaseee

V kubus = r x r x r
= r^3
= 9^3
= 729 cm^3

V balok = p x l x t
= 12 x 9 x 4
= 432 cm^3

V bangun = V kubus + V balok
= 729+432
= 1161 cm^3

*semoga membantu. sukses selalu ^_^

V=p×l×t
balok 1=9×9×9
=729cm kubik
balok 2=12×4×9
=432cm kubik
V.total=729+432=1161cm kubik
