Limas dengan alas Δ siku-siku
mempunyai kedalaman 18 cm
serta alas 3 cm dan tinggi alas 4 cm
⅓ × ( ½ × a × t ) × tinggi prisma
⅓ × ( ½ × 3 × 4 ) × 18
1 × ( 3 × 2 ) × 6
1 × 6 × 6
36 cm³
Jawaban:
Volume limas:
V = ⅓ × luas alas × t
= ⅓ × (½ × a × t) × 18
= ⅓ × (½ × 3 × 4) × 18
= ⅓ × (½ × 12) × 18
= ⅓ × 6 × 18
= 2 × 18
= 36cm³
