The minimum sample volume required for casting three 100mm x 200mm cylinders can be calculated using the dimensions of the cylinders. Each cylinder has a diameter of 100mm and a height of 200mm.

To find the volume of one cylinder, we use the formula for the volume of a cylinder:

\[ V = \pi r^2 h \]

Where:

- \( r \) is the radius (50mm or 0.05 meters),

- \( h \) is the height (200mm or 0.2 meters).

Calculating the volume of one cylinder gives:

\[ V = \pi (0.05)^2 (0.2) \approx \pi (0.0025)(0.2) \approx \pi (0.0005) \approx 0.00157 \, \text{m}^3 \]

Since you need three cylinders, the total volume required would be:

\[ 3 \times 0.00157 \, \text{m}^3 \approx 0.00471 \, \text{m}^3 \]

Converting cubic meters to liters (1 m³ = 1000 liters):

\[ 0.
