A light teal-colored triangular prism is shown in a three-dimensional perspective. 

The base of the prism is a rectangle with dimensions of 7 cm (width) and 10 cm (length). 

The apex of the prism is 11 cm high from the base.

Dashed lines indicate the hidden edges of the prism. 

A vertical dashed line, representing the height to the apex, is drawn from the center of the base rectangle to the apex, indicating the height of the prism to the top.What is the volume of the pyramid?

To find the volume of a pyramid (or a triangular prism, as it seems like there might be a mix-up in terminology), we typically use the following formula for the volume of a pyramid:

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

Given that the base of the prism is a rectangle with dimensions of 7 cm (width) and 10 cm (length), the area of the base is:

\[ \text{Base Area} = \text{Width} \times \text{Length} = 7 , \text{cm} \times 10 , \text{cm} = 70 , \text{cm}^2 \]

The height of the prism (as stated in the problem) is 11 cm.

Now we can calculate the volume:

\[ \text{Volume} = \frac{1}{3} \times 70 , \text{cm}^2 \times 11 , \text{cm} \]

Calculating this gives:

\[ \text{Volume} = \frac{1}{3} \times 770 , \text{cm}^3 = \frac{770}{3} , \text{cm}^3 \approx 256.67 , \text{cm}^3 \]

Thus, the volume of the prism is approximately 256.67 cm³.
