Answer:
<em>1,172.5cm²</em>
Step-by-step explanation:
Total surface area of a box = 2(LW + WH + LH)
L is the length = 11.5cm
W is the width = 7cm
H is the height = 1.5cm
Substitute
TSA = 2(11.5(7) + 7(1.5) + (11.5)(1.5))
TSA = 2(80.5+10.5+17.25)
TSA = 2(117.25)
TSA = 234.5cm²
<em>Hence the total surface area of a stack of five such compact disc boxes will be 5(234.5) = 1,172.5cm²</em>

Answer:
D- add the fractions together on the right side of the equation
Step-by-step explanation:
In the previous step, the fractions are written with a common denominator. In the last step, the two fractions are combined (added together).
The best description of those provided is ...
D- add the fractions together on the right side of the equation
