The net of a rectangular prism is shown. What is the surface area of the rectangular prism? ( 7 cm, 2 cm, 10. )

Answer 1

To find the surface area of a rectangular prism, you need to find the area of each of the faces and then add them all up.

The rectangular prism has 6 faces:
1. Top face: 7cm x 10cm = 70 cm²
2. Bottom face: 7cm x 10cm = 70 cm²
3. Front face: 7cm x 2cm = 14 cm²
4. Back face: 7cm x 2cm = 14 cm²
5. Left side face: 10cm x 2cm = 20 cm²
6. Right side face: 10cm x 2cm = 20 cm²

Now, add up all the areas:
70 cm² + 70 cm² + 14 cm² + 14 cm² + 20 cm² + 20 cm² = 208 cm²

Therefore, the surface area of the rectangular prism is 208 cm².
