folume bangun di samping adalah.......cm3

V.balok = p.l.t
             = 12.12.15 =2160 cm³
V. limas = 1/3 . L.alas .t
              = 1/3 12.12.12 = 576 cm³
Vbangun = 2160+576= 2736 cm³
Maaf klau ada kesalahan

Volume Total
= Volume Limas + Volume Balok
= (1/3*luas alas*tinggi) + (p*l*t)
= (1/3*(12*12)*12) + (12*12*15)
= 576 + 2160
= 2736 cm^3
