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, each with a diameter of 4.2 cm, can be obtained from a rectangular solid of lead with dimensions 66 cm, 42 cm, and 21 cm, we will follow these steps:

### Step-by-Step Solution:

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}
