Mario's new swimming pool is in the shape of a rectangular prism and measures 25 m in length, 10 m in width, and 2 m in height. What is the surface area of Mario's pool?

Answer explanation

The surface area of a rectangular prism is calculated by adding the areas of all six faces. The formula is 2lw + 2lh + 2wh. Substituting the given values, we get 2(25*10) + 2(25*2) + 2(10*2) = 700 m^2.

Answer explanation

The surface area of a cylinder is given by the formula 2πrh + 2πr^2. Substituting the values, we get 2*3.14*5*10 + 2*3.14*5^2 = 502.6 m^2. Therefore, the correct answer is 502.6 m^2.
