To find the surface area of the triangular prism, we need to calculate the area of each of the five faces and add them together.

1. Front face: The front face is a triangle with base 27.9 cm and height 30.5 cm.
Area = 0.5 * base * height = 0.5 * 27.9 cm * 30.5 cm = 424.425 cm²

2. Bottom face: The bottom face is a triangle with base 28.4 cm and height 27.9 cm.
Area = 0.5 * base * height = 0.5 * 28.4 cm * 27.9 cm = 395.58 cm²

3. Right face: The right face is a rectangle with length 30.5 cm and width 5.1 cm.
Area = length * width = 30.5 cm * 5.1 cm = 155.55 cm²

4. Left face: The left face is a rectangle with length 30.5 cm and width 5.1 cm (same as right face).
Area = length * width = 30.5 cm * 5.1 cm = 155.55 cm²

5. Back face: The back face is a rectangle with length 28.4 cm and width 27.9 cm.
Area = length * width = 28.4 cm * 27.9 cm = 791.36 cm²

Total surface area = 424.425 cm² + 395.58 cm² + 155.55 cm² + 155.55 cm² + 791.36 cm² = 1922.465 cm²

Therefore, approximately 1922 cm² of wrapping paper is needed to wrap the toy.
