Question

Find the surface area of a cube with a side length of 6.5

Answer 1

6.5^2 x 6.5^2= 1785.0625
Answer: 1785.1 sq units

Answer 2

Check the picture below.

so since a cube is really 6 equal rectangles stacked up to each other at the corners, in this case each one with an area of 6.5x6.5, so the area is simply 6(6.5*6.5) = 253.5.
