Volume Bangun = Volume I + Volume II
= 140.000 + 192.325
= 332.325 m²
Volume I ( Balok ) = P × L × T
= 100 × 70 × 20
= 100 × 1400
= 140.000 m²
Volume II ( Setengah Tabung ) = Luas Alas × Tinggi
= ( × × r² ) × T
= ( × 3,14 × ( 70 ÷ 2)²) × 100
= ( × 3,14 × 35² ) × 100
= ( × 3,14 × 1225 ) × 100
= ( × 3846,5 ) × 100
= 1923,25 × 100
= 192.325 m²
