Final answer:
To find the surface area of a rectangular prism, multiply the dimensions of each face and sum them up.
Step-by-step explanation:
To find the surface area of a rectangular prism, you need to calculate the area of each face and then sum them all up. Given the dimensions of 5cm, 6cm, and 11cm, we can find the surface area as follows:
- Calculate the area of the top and bottom faces by multiplying the length and width (5cm * 11cm = 55cm²).
- Calculate the area of the two side faces by multiplying the height and width (6cm * 11cm = 66cm²).
- Calculate the area of the two front and back faces by multiplying the height and length (6cm * 5cm = 30cm²).
- Add up all the face areas: 55cm² + 55cm² + 66cm² + 66cm² + 30cm² + 30cm² = 302cm²
Therefore, the surface area of the rectangular prism is 302cm².
