The top and bottom faces are 3 inches by 3 inches.

Area = 3 in. * 3 in. * 2 = 18 in.^2

The front, back, right, and left faces are 3 in. by 6 in.

Area = 3 in. * 6 in. * 4 = 72 in.^2

Total surface area = 18 in.^2 + 72 in.^2 = 90 in.^2

Answer: B. 90 square inches

I really need help <br> it’s very hard

Answer:

The angle ZLK has a value of 75 degrees.

Step-by-step explanation:

We can calculate this as:

$m\angle MLZ+m\angle ZLK=m\angle MLK\\\\(x+66)+(x+86)=130\\\\2x+152=130\\\\2x=130-152\\\\x=-22/2=-11\\\\\\m\angle ZLK=x+86=-11+86=75$

We replace the angles values in the equation, as both angles that are formed with Z (MLZ and ZLK), when added, gives as the angle MLK. This allows us to calculate x. The value for x is -11.

Then, with the value for x we can calculate any of both angles.
