Option 1 : 2100 m^{3}

**Given:**

Shorter side of trapezium = 12 m

Longer side of trapezium = 13 m

Distance between parallel sides = 24 m

Height of prism = 7 m

**Formula Used:**

Area of trapezium = 1/2 × (a + b) × h

where, a, b → Parallel sides of trapezium, h → Height of trapezium.

Volume of prism = Area of Base × Height of prism

**Calculations:**

Area of trapezium = 1/2 × (a + b) × h

Area of trapezium = 1/2 × (12 + 13) × 24

⇒ Area of trapezium = 300 m^{2}

Volume of prism = Area of Base × Height

⇒ Volume of prism = 300 × 7

⇒ Volume of prism = 2100 m^{3}

**∴ The volume of prism is 2100 m ^{3}.**
