To determine the volume of the glass, we first need to identify the shape. Assuming the glass is in the shape of a cylinder, we can use the formula for the volume of a cylinder:

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

Where:

  • \( V \) is the volume,
  • \( r \) is the radius,
  • \( h \) is the height.

The height \( h \) is given as 10 cm, and the width (diameter) is given as 8 cm. Therefore, the radius \( r \) will be:

\[ r = \frac{\text{diameter}}{2} = \frac{8 \text{ cm}}{2} = 4 \text{ cm} \]

Now substituting the values into the volume formula:

\[ V = \pi (4 \text{ cm})^2 (10 \text{ cm}) \]

\[ V = \pi (16 \text{ cm}^2) (10 \text{ cm}) \]

\[ V = 160\pi \text{ cm}^3 \]

Now, using \( \pi \approx 3.14 \):

\[ V \approx 160 \times 3.14 \text{ cm}^3 \approx 502.4 \text{ cm}^3 \]

Therefore, the volume of the glass is approximately 502.4 cubic centimeters.

The correct response is:

502.4 cubic centimeters.
