- s² = a² + t²
- t² = s² - a²
- t² = 15² - 12²
- t² = 225 - 144
- t² = 81
- t = √81
- t = 9 cm
volume prisma
- ½ × ( a × t ) × tinggi prisma
- ½ × ( 12 × 9 ) × 20
- ½ × 108 × 20
- ½ × 2.160
- 2.160/2
- 1.080 cm³

بِسْـــمِ اللَّهِ الرَّحْمَــنِ الرَّحِيْمِ
Diketahui:
- a = 12 cm
- m = 15 cm
- t = √(15² - 12²) = √(225 - 144) = √81 = 9 cm
- Tp = 20 cm
Ditanyakan:
- V = ... cm³?
Penyelesaian:
V = La × Tp
= ½ × a × t × Tp
= ½ × 12 × 9 × 20
= 6 × 9 × 20
= 54 × 20
= 1.080 cm³
