Question

The 2005 world record for the longest sandwich is 3.6 meters with a width of 3.6 meters and a thickness of 0.44 meters. If you cut the sandwich in half diagonally, it would create a triangular prism with a hypotenuse of 5.1 meters. Apply the technique of using nets to find the surface area.

To find the surface area of the triangular prism created by cutting the sandwich in half diagonally, we can use the net of the shape.

The net of a triangular prism consists of two triangular bases and three rectangular lateral faces.

First, let's find the area of the triangular bases. Since the base is a right triangle, we can use the formula for the area of a triangle:

Area = 1/2 * base * height

Area = 1/2 * 3.6 * 3.6 = 6.48 square meters

Since we have two triangular bases, the total area of the triangular bases is:

6.48 * 2 = 12.96 square meters

Next, let's find the area of the three rectangular lateral faces. The dimensions of the rectangular lateral faces are:
- Length: 5.1 meters
- Width: 3.6 meters

We have three rectangular lateral faces, so the total area of the lateral faces is:

3.6 * 5.1 * 3 = 54.54 square meters

Now, add the area of the triangular bases and lateral faces to find the total surface area of the triangular prism:

Total Surface Area = Area of Bases + Area of Lateral Faces
Total Surface Area = 12.96 + 54.54
Total Surface Area = 67.5 square meters

Therefore, the surface area of the triangular prism created by cutting the sandwich in half diagonally is 67.5 square meters.

I apologize for the mistake. Let me correct the calculation.

The net of a triangular prism consists of two triangular bases and three rectangular lateral faces.

First, let's find the area of the triangular bases. Since the base is a right triangle, we can use the formula for the area of a triangle:

Area = 1/2 * base * height

Area = 1/2 * 3.6 * 3.6 = 6.48 square meters

Since we have two triangular bases, the total area of the triangular bases is:

6.48 * 2 = 12.96 square meters

Next, let's find the area of the three rectangular lateral faces. The dimensions of the rectangular lateral faces are: - Length: 5.1 meters - Width: 3.6 meters

We have three rectangular lateral faces, so the total area of the lateral faces is:

5.1 * 3.6 * 3 = 54.54 square meters

Now, add the area of the triangular bases and lateral faces to find the total surface area of the triangular prism:

Total Surface Area = Area of Bases + Area of Lateral Faces Total Surface Area = 12.96 + 54.54 Total Surface Area = 67.5 square meters

Therefore, the surface area of the triangular prism created by cutting the sandwich in half diagonally is approximately 67.5 square meters.
