To calculate the surface area of the triangular prism container, we need to find the area of each face and then add them together.
1. The two triangular faces:
A = 1/2 * base * height
A = 1/2 * 27.9 cm * 5.1 cm = 71.145 cm^2
Total area of two triangular faces = 2 * 71.145 cm^2 = 142.29 cm^2
2. The three rectangular faces:
- Face 1: 27.9 cm * 30.5 cm = 850.95 cm^2
- Face 2: 28.4 cm * 30.5 cm = 865.4 cm^2
- Face 3: 28.4 cm * 27.9 cm = 793.36 cm^2
Total area of three rectangular faces = 850.95 cm^2 + 865.4 cm^2 + 793.36 cm^2 = 2509.71 cm^2
Adding both sets of faces together:
Total surface area = 142.29 cm^2 + 2509.71 cm^2 = 2652 cm^2
So, approximately 2652 cm^2 of wrapping paper is needed to wrap the toy.
The prism is 5.1 cm tall, 27.9 cm long, 28.4 cm long triangle side, 30.5 cm wide.
