Answer:
Option D, [tex]245.8\ units^2[/tex]
Step-by-step explanation:
Step 1: Determine the area
[tex]A = l * w[/tex]
[tex]A = 6.4\ units * 6.4\ units[/tex]
[tex]A = 40.96\ units^2[/tex]
Step 2: Determine the surface area
We know that we have 6 sides of equal area that means that we can just use [tex]6 * 40.96\ units^2[/tex] which gives us [tex]245.76\ units^2[/tex].
Answer: Option D, [tex]245.8\ units^2[/tex]
