V( Prisma Segitiga )

V = luas alas × tinggi prisma

V = ½ × alas × tinggi × tinggi prisma

V = ½ × 100 cm × 150 cm × 200 cm

V = 50 cm × 150 cm × 200 cm

V = 50 cm × 30.000 cm²

{ V = 1.500.000 cm³ atau 1.500 dm³ }

V( Bola )

V = 4/3 × π × r³

V = 4/3 × 22/7 × 7 cm × 7 cm × 7 cm

V = 4/3 × 22 × 1 cm × 49 cm²

V = 88/3 × 49 cm³

V = 4.312 cm³ ÷ 3

{ V = 1.437⅓ cm³ }

V( Tabung )

V = π × r² × t

V = 22/7 × 7 cm × 7 cm × 14 cm

V = 22 × 1 cm × 98 cm²

V = 22 × 98 cm³

V = ( 98 × 20 ) + ( 98 × 2 )

V = 1.960 cm³ + 196 cm³

{ V = 2.156 cm³ }

V( Limas Segitiga Siku - Siku )

V = ⅓ × luas alas × tinggi limas

V = ⅓ × ½ × alas × tinggi × tinggi limas

V = ⅓ × ½ × 6 cm × 8 cm × 9 cm

V = 3 cm × 8 cm × 3 cm

V = 9 cm² × 8 cm

{ V = 72 cm³ }
