Question

An open rectangular tank has the internal measurements as 3m long ,2m wide and 1.5 high calculate the surface area that is not in contact with water given the water depth is 1.2m​

Answer 1

3 m²

Explanation:

h = 1.5 m - 1.2 m = 0.3 m

P = 2(3 m + 2 m) = 10 m

A = Ph

A = 10 m × 0.3 m

A = 3 m²
