Volume dan luas permukaan dari prisma segitiga berturut-turut adalah.. 42 cm³ dan 96 cm².
V = La × tp
= (½ × a∆ × t∆) × tp
= (½ × 3 × 4) × 7
= (½ × 12) × 7
= 6 × 7
= 42 cm³
Lp = (2 × La) + (Ka × tp)
= (2 × ½ × a∆ × t∆) + ((a∆ + t∆ + c) × tp)
= (2 × ½ × 3 × 4) + ((3 + 4 + 5) × 7)
= 12 + (12 × 7)
= 12 + 84
= 96 cm²
