Odpowiedź:
a) V = 12cm×2 × 5cm×2 × 10cm
V = 24 × 10 × 10 cm³
V = 2400 cm³
b) h² + (6cm)² = (10cm)²
h² = 100cm² - 36cm²
h² = 64cm²
h = 8cm
V = (6cm+14cm)×8cm × 10cm
V = 20cm × 80cm²
V = 1600cm³
c) V = Pp × H
Pp = (2cm+4cm+6cm)×3cm ÷ 2
Pp = 12cm×3cm ÷ 2
Pp = 6×3 cm²
Pp = 18cm²
V = 18cm² × 10cm
V = 180cm²
