The volume \( V \) of a pyramid can be calculated using the formula:
\[ V = \frac{1}{3} \times \text{Base Area} \times \text{Height} \]
For a rectangular base, the base area \( A \) is calculated as:
\[ A = \text{Width} \times \text{Length} = 7 , \text{cm} \times 10 , \text{cm} = 70 , \text{cm}^2 \]
Now we can find the volume using the height of the pyramid:
\[ V = \frac{1}{3} \times 70 , \text{cm}^2 \times 11 , \text{cm} = \frac{770}{3} , \text{cm}^3 \approx 256.67 , \text{cm}^3 \]
Thus, the volume of the pyramid is approximately \( 256.67 , \text{cm}^3 \).
If you need the volume in a specific form:
\[ V = \frac{770}{3} , \text{cm}^3 \text{ or } 256.67 , \text{cm}^3 \]
