V.balok=p×l×t
=5×6×7
=210 dm3/ltr
V.tabung=phi×r2×t
=22/7×3,5×3,5×3
=11×3,5×3
=38,5×3
=115,5 dm3/ltr
V.balok+V.tabung
=210+115,5
=325,5 dm3/ltr

Volume balok = 5 dm x 6 dm x 7 dm = 210 dm kubik

Jari - jari = 3,5 dm : 2 = 1,75 dm

Volume tabung = 1,75 dm x 1,75 dm x 22/7 x 3 dm
= 28,875 dm kubik

Volume = 210 dm kubik + 28,875 dm kubik
= 238,875 dm kubik
= 238,875 x 1.000 cm kubik
= 238.875 cm kubik

Maaf klo salah ya
