Answer:
Step-by-step explanation:
To find the surface area of a cube, you need to calculate the area of all six sides and then sum them up.
Since a cube has all sides equal, you can use the formula:
Surface Area = 6 * (side length)^2
Given that the side length of the cube is 8.25 mm:
Surface Area = 6 * (8.25 mm)^2
Surface Area = 6 * (8.25 mm * 8.25 mm)
Surface Area = 6 * 68.0625 mm^2
Surface Area ≈ 408.375 mm^2
So, the surface area of the cube is approximately 408.38 mm^2, which corresponds to option B.
