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 1: Calculate the Volume of the Rectangular Solid
The volume \( V \) of a rectangular solid can be calculated using the formula:
\[ V = L \times B \times H \]
where \( L \) is the length, \( B \) is the breadth, and \( H \) is the height.
