To determine the dimensions of the vertical cross section of the right rectangular prism, we need to consider the orientation of the prism and what a vertical cross section would look like.
Given the dimensions of the prism are:
- Length: 11 inches
- Width: 6 inches
- Height: 1 inch
A vertical cross section would be a vertical slice through the prism, which would typically reveal the height and length.
Looking at the options provided:
A. 11 in. x 1 in.
- This indicates a rectangle with a length of 11 inches and a height of 1 inch.
B. 11 in. x 6 in.
- This indicates a rectangle with a length of 11 inches and a height of 6 inches.
C. 6 in. x 1 in.
- This indicates a rectangle with a length of 6 inches and a height of 1 inch.
Since the vertical cross section has dimensions corresponding to the height and length of the prism, the correct option would be:
A. 11 in. x 1 in.
This option accurately represents a vertical cross section using the length of the prism (11 in.) and the height (1 in.).
