**Given:**

Radius of cylindrical tank(r) = 1.3 m

Height of cylindrical tank(h) = 1.5 m

**Formula used:**

Total surface area of cylinder = 2πr(r + h)

**Calculations:**

Metal sheet required = 2πr(r + h)

⇒ 2 × (22/7) × 1.3 × (1.3 + 1.5)

⇒ 22.88

**∴ Metal sheet required to make cylindrical tank is 22.88 m ^{2}**.
