How many spherical lead shots each 4.2 cm in diameter can be obtained from a rectangular solid of lead with dimensions 66cm, 42cm, 21cm. `(u s epi=(22)/7)dot`

Explanation

To solve the problem of how many spherical lead shots can be obtained from a rectangular solid of lead, we will follow these steps:

### Step 1: Calculate the volume of the rectangular solid
The volume \( V \) of a rectangular solid (cuboid) is given by the formula:
\[ V = \text{length} \times \text{breadth} \times \text{height} \]
Given dimensions are:
