To find the surface area of the rectangular prism, we need to determine the dimensions of each face.
The face at the bottom has dimensions 11in x 9in = 99in^2
The face on the right side has dimensions 9in x 3in = 27in^2
The face on the left side has the same dimensions as the face on the right side, so it also has an area of 27in^2
The face at the top has the same dimensions as the face at the bottom, so it also has an area of 99in^2
The face at the front and back of the prism have dimensions 11in x 3in = 33in^2.
To find the total surface area, we add up the areas of all the faces:
99in^2 + 27in^2 + 27in^2 + 99in^2 + 33in^2 = 285in^2
Therefore, the surface area of the given rectangular prism is 285 square inches.
