= 16 cm : 2
= 8 cm
b = d₂ : 2
= 12 cm : 2
= 6 cm
a² + b² = c²
8² + 6² = c²
64 + 36 = c²
100 = c²
√100 = √c²
10 = c
s = c
= 10 cm
L sisi tegak = s × t
200 cm² = 10 cm × t
200 cm² : 10 cm = t
20 cm = t
V = La × t
= 1/2 × d₁ × d₂ × t
= 1/2 × 16 cm × 12 cm × 20 cm
= 8 cm × 12 cm × 20 cm
= 1.920 cm³
Jadi volumenya adalah 1.920 cm³
