1)
( 1/2 × 24cm × 18cm ) × 35 cm
= 216 cm² × 35 cm
= 7506
2)
( 1/2 × 15 cm × 28 cm ) × 42 cm
= 210 cm² × 42 cm
= 8820 cm³
3)
( 1/2 × 15 cm × 20 cm ) × 37 cm
= 150 cm² × 37 cm
= 5550 cm³
4)
( 1/2 × 16 cm × 6 cm ) × 20 cm
= 48 cm² × 20 cm
= 960 cm³
5)
( 1/2 × 10 cm × 7,5 cm ) × 14 cm
= 37,5 cm² × 14 cm
= 525 cm³
6)
( 1/2 × 25 cm × 20 cm ) × 46 cm
= 250 cm² × 46 cm
= 11500

Jawab:
1.) Volume = Luas Alas × Tinggi Prisma
= ([tex]\frac{1}{2}[/tex] × 18 × 24) × 35
= ([tex]\frac{1}{2}[/tex] × 432) × 35
= 216 × 35
= 7.560 cm³
2.) Volume = Luas Alas × Tinggi Prisma
= ([tex]\frac{1}{2}[/tex] × 28 × 15) × 42
= ([tex]\frac{1}{2}[/tex] × 420) × 42
= 210 × 42
= 8.820 cm³
3.) Volume = Luas Alas × Tinggi Prisma
= ([tex]\frac{1}{2}[/tex] × 15 × 20) × 37
= ([tex]\frac{1}{2}[/tex] × 300) × 37
= 150 × 35
= 5.550 cm³
4.) Volume = Luas Alas × Tinggi Prisma
= ([tex]\frac{1}{2}[/tex] × 16 × 6) × 20
= ([tex]\frac{1}{2}[/tex] × 96) × 20
= 48 × 20
= 960 cm³
5.) Volume = Luas Alas × Tinggi Prisma
= ([tex]\frac{1}{2}[/tex] × 10 × 75) × 14
= ([tex]\frac{1}{2}[/tex] × 750) × 14
= 375 × 14
= 5.250 cm³
6.)
Sisi Alas² = Sisi Miring² - Tinggi²
= 25² - 20²
= 225
Sisi Alas = √225
= 15 cm
Volume = Luas Alas × Tinggi Prisma
= ([tex]\frac{1}{2}[/tex] × 15 × 20) × 46
= ([tex]\frac{1}{2}[/tex] × 300) × 46
= 150 × 46
= 6.900 cm³
