B Correct answer
Explanation

The surface area of a right rectangular prism is calculated using the formula 2(lw + lh + wh). Substituting the given values: 2(8*5 + 8*10 + 5*10) = 2(40 + 80 + 50) = 2(170) = 340.

AI explanation

Using the surface area formula for a right rectangular prism, SA = 2(lw + lh + wh), we substitute the given dimensions. This yields 2((8 * 5) + (8 * 10) + (5 * 10)), which simplifies to 2(40 + 80 + 50). Adding the values inside the parentheses gives 170, and multiplying by 2 results in a surface area of 340 square centimeters.
