  • V Tabung = 5/6 × π × r² × t
    V = 5/6 × 22/7 × 7² × 10
    V = 5/6 × 22/7 × 8× 10
    V = 5/6 × 22 × 70
    V = 1.283,333.... cm³
  • V. kubus=s . s . s
    =7 .7 .7
    =343cm³
    V. tabung=π . r² . t
    =22/7 . (3,5.3,5) . 8
    =308cm³
    Jadi, volume bangun tersebut adalah:
    V. kubus+V.tabung
    =343cm³+308cm³
    =651cm³
