**Given:**

Volume of the Reservoir = 84000 L = 84 m^{3}

Length = 5 m and breadth = 2.1 m (can take vice versa also)

**Formula used:**

The volume of Cuboid = Length × Breadth × Height

**Calculation:**

Let 'h' be the depth of the reservoir (Depth can be considered as height)

84 = 5 × 2.1 × h

⇒ h = 84/(5 × 2.1)

⇒ h = 8 m

**∴ The depth of water in the reservoir is 8 m**
