Shanta runs an industry in a shed which is in the shape of a cuboidsurmounted by a half cylinder. If the base of the shed is of dimension `7m xx15 m`, and the height of the cuboidal portion is 8 m, find the volume of air that the shed can hold.Further suppose the machinery in the shed occupies 300 `m^3` and 20 workers each of whom occupy 0.08 `m^3` space on an average.Then how much air is in the shed.

Explanation

To solve the problem step by step, we will calculate the volume of the shed, which consists of a cuboidal part and a half cylindrical part, and then determine how much air remains after accounting for the machinery and the workers.

### Step 1: Calculate the Volume of the Cuboidal Portion
The volume \( V \) of a cuboid is given by the formula:
\[ V = \text{length} \times \text{breadth} \times \text{height} \]
