To find the volume of a square-based pyramid, you can use the formula:

\[
V = \frac{1}{3} \times \text{Base Area} \times \text{Height}
\]

1. First, calculate the area of the base. Since the base is a square with each side measuring 8 cm:

\[
\text{Base Area} = \text{side length} \times \text{side length} = 8 \, \text{cm} \times 8 \, \text{cm} = 64 \, \text{cm}^2
\]

2. Next, use the height of the pyramid, which is given as 10 cm.

3. Plug the base area and height into the volume formula:

\[
V = \frac{1}{3} \times 64 \, \text{cm}^2 \times 10 \, \text{cm}
\]

4. Calculate the volume:

\[
V = \frac{1}{3} \times 640 \, \text{cm}^3 = \frac{640}{3} \, \text{cm}^3 \approx 213.33 \, \text{cm}^3
\]

5. Rounded to the nearest whole cubic centimeter, the volume is:

\[
V \approx 213 \, \text{cm}^3
\]

So the answer is **213**.
