To find the surface area of the triangular prism, we need to find the areas of each face and then add them up.
1. Front triangular face:
Area = 1/2 * base * height
Area = 1/2 * 5 * 4
Area = 10 square centimeters
2. Back triangular face (same as front triangular face):
Area = 10 square centimeters
3. Right rectangular face:
Area = length * width
Area = 11 * 5
Area = 55 square centimeters
4. Left rectangular face (same as right rectangular face):
Area = 55 square centimeters
5. Top rectangular face:
Area = base * height
Area = 5 * 4
Area = 20 square centimeters
6. Bottom rectangular face (same as top rectangular face):
Area = 20 square centimeters
Now, add up all the areas:
10 (front triangular face) + 10 (back triangular face) + 55 (right rectangular face) + 55 (left rectangular face) + 20 (top rectangular face) + 20 (bottom rectangular face) = 170 square centimeters
Therefore, the surface area of the triangular prism is 170 square centimeters.
Question
Use the image to answer the question.
An illustration shows a triangular prism. The front triangular face is visible. The right rectangular face is visible. The visible rectangular face has a width of 5 centimeters and length of 11 centimeters. The sides and edges that are not visible are indicated by dashed lines. The legs of the triangular face are labeled 3 centimeters and 4 centimeters. The hypotenuse shares the same label as the width of the visible rectangular face.

Apologies for the mistake. Let's correct it.
1. Front triangular face:
Area = 1/2 * base * height
Area = 1/2 * 5 * 4
Area = 10 square centimeters
2. Back triangular face (Same as front triangular face):
Area = 10 square centimeters
3. Right rectangular face:
Area = length * width
Area = 11 * 5
Area = 55 square centimeters
4. Left rectangular face (Same as right rectangular face):
Area = 55 square centimeters
5. Top rectangular face:
Area = base * height
Area = 5 * 3 (note that the height of the triangular face is 3 cm, not 4 cm)
Area = 15 square centimeters
6. Bottom rectangular face (Same as top rectangular face):
Area = 15 square centimeters
Now, add up all the areas:
10 (front triangular face) + 10 (back triangular face) + 55 (right rectangular face) + 55 (left rectangular face) + 15 (top rectangular face) + 15 (bottom rectangular face) = 160 square centimeters
Therefore, the correct surface area of the triangular prism is 160 square centimeters.
1. Front triangular face:
Area = 1/2 * base * height
Area = 1/2 * 5 * 4
Area = 10 square centimeters
2. Back triangular face (Same as front triangular face):
Area = 10 square centimeters
3. Right rectangular face:
Area = length * width
Area = 11 * 5
Area = 55 square centimeters
4. Left rectangular face (Same as right rectangular face):
Area = 55 square centimeters
5. Top rectangular face:
Area = base * height
Area = 5 * 3 (note that the height of the triangular face is 3 cm, not 4 cm)
Area = 15 square centimeters
6. Bottom rectangular face (Same as top rectangular face):
Area = 15 square centimeters
Now, add up all the areas:
10 (front triangular face) + 10 (back triangular face) + 55 (right rectangular face) + 55 (left rectangular face) + 15 (top rectangular face) + 15 (bottom rectangular face) = 160 square centimeters
Therefore, the correct surface area of the triangular prism is 160 square centimeters.

To find the amount of wrapping paper Jerry will need to wrap the present, we need to calculate the surface area of the rectangular prism (the box).
The surface area of a rectangular prism can be found by adding the areas of all its faces:
1. Front face:
Area = width * height
Area = 10 * 4
Area = 40 square centimeters
2. Back face (Same as front face):
Area = 40 square centimeters
3. Top face:
Area = length * width
Area = 17 * 10
Area = 170 square centimeters
4. Bottom face (Same as top face):
Area = 170 square centimeters
5. Right side face:
Area = length * height
Area = 17 * 4
Area = 68 square centimeters
6. Left side face (Same as right side face):
Area = 68 square centimeters
Now, add up all the areas:
40 (front face) + 40 (back face) + 170 (top face) + 170 (bottom face) + 68 (right side face) + 68 (left side face) = 556 square centimeters
Therefore, Jerry will need 556 square centimeters of wrapping paper to wrap the present.

Let's recheck the calculations for the surface area of the rectangular prism.
1. Front and back face:
- Area = width * height = 10 * 4 = 40 square centimeters (front and back are the same)
2. Top and bottom face:
- Area = length * width = 17 * 10 = 170 square centimeters (top and bottom are the same)
3. Right and left face:
- Area = length * height = 17 * 4 = 68 square centimeters (right and left are the same)
Now, add up all the areas:
40 (front/back) + 170 (top/bottom) + 68 (right/left) = 278 square centimeters
Therefore, Jerry will need 278 square centimeters of wrapping paper to wrap the present. Thank you for your patience.
