Answer:

Option D, 245.8\ units^2

Step-by-step explanation:

<u>Step 1:  Determine the area</u>

A = l * w

A = 6.4\ units * 6.4\ units

A = 40.96\ units^2

<u>Step 2:  Determine the surface area</u>

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

zavuch27 [327]
1/3 will become 2/6.

Steps in adding fraction.
Step 1. Make sure that the denominators are the same:
5/6 + 1/3      * 6 and 3 are the denominators. they are not the same. however, 6 is twice the number of 3. Thus, multiply 2 to the numerator and denominator of 1/3

1/3 * 2/2 = 2/6

5/6 + 2/6

Step 2. Add the numerators. Put the sum above the common denominator.

(5+2) / 6 = 7/6

Step 3. Simplify the fraction.

7/6 = 1 1/6 

Addison used 1 1/6 yards of ribbon in all.
