Answer:

Option D,
245.8\ units^2

Explanation:

Step 1: Determine the area


A = l * w


A = 6.4\ units * 6.4\ units


A = 40.96\ units^2

Step 2: Determine the surface area

We know that we have 6 sides of equal area that means that we can just use
6 * 40.96\ units^2 which gives us
245.76\ units^2.

Answer: Option D,
245.8\ units^2
