138 cm^2
To find the surface area of the rectangular prism, you would calculate the area of each face and add them together.
In this case, the areas of the faces are:
- Top face: 4 cm x 10 cm = 40 cm^2
- Bottom face: 4 cm x 10 cm = 40 cm^2
- Front face: 4 cm x 8 cm = 32 cm^2
- Back face: 4 cm x 8 cm = 32 cm^2
- Right side face: 10 cm x 8 cm = 80 cm^2
- Left side face: 10 cm x 8 cm = 80 cm^2
Adding all the areas together gives you a total surface area of 40 cm^2 + 40 cm^2 + 32 cm^2 + 32 cm^2 + 80 cm^2 + 80 cm^2 = 304 cm^2.
Therefore, the surface area of the rectangular prism is 304 cm^2. The closest answer choice is 306 cm^2.
