What the surface area of 5 x 5 x 5?

To calculate the surface area of a cube with side length (5) units, you can use the formula for the surface area of a cube, which is (6s^2), where (s) is the length of a side. For a cube with side length (5), the surface area is (6 \times (5^2) = 6 \times 25 = 150) square units. Therefore, the surface area of the cube is (150) square units.
