Find the surface area of the rectangular prism.
Length: 2 km
Width: 3 km
Height: 1 km
To find the surface area of a rectangular prism, we need to calculate the area of each face and then sum them up.
The rectangular prism has 6 faces: 1 top face, 1 bottom face, 2 side faces, and 2 front/back faces.
1. Top face: 2 km * 3 km = 6 km²
2. Bottom face: 2 km * 3 km = 6 km²
3. Side faces (2 of them): 2 km * 1 km = 2 km² * 2 = 4 km²
4. Front/back faces (2 of them): 3 km * 1 km = 3 km² * 2 = 6 km²
Now, add up the areas of all the faces:
6 km² + 6 km² + 4 km² + 6 km² = 22 km²
The surface area of the rectangular prism is 22 km².
