Answer:
3 In²
Step-by-step explanation:
Talking about surface area, the total area of an object is taken into consideration.
NB: Kindly check the attached picture for the diagram of the 3D object.
In this question, the surface area has to be determined and we will have to take into consideration all the area of the 3D object given in the question.
Surface Area = 6 × k².
Surface area = 6 × ( 1.8 × 1.8) cm².
Surface Area = 19.44 cm².
The next thing to do here is to convert the cm² to in². Therefore, 19.44 cm² ------> x in².
19.44 × 0.155 in² = 3 in².
X - (9x - 10) + 11 = 12x + 3(-2x + 
) equals x = 
.
First, simplify brackets. / Your problem should look like: x - 9x + 10 + 11 = 12x + 3(-2x + ).
Second, simplify x - 9x + 10 + 11 to -8x + 10 + 11. / Your problem should look like: -8x + 10 + 11 = 12x + 3(-2x + ).
Third, simplify -8x + 10 + 11 to -8x + 21. / Your problem should look like: -8x + 21 = 12x + 3(-2x + ).
Fourth, expand. / Your problem should look like: -8x + 21 = 12x - 6x + 1.
Fifth, simplify 12x - 6x + 1 to 6x + 1./ Your problem should look like: -8x + 21 = 6x + 1.
Sixth, add 8x to both sides. / Your problem should look like: 21 = 6x + 1 + 8x.
Seventh, simplify 6x + 1 + 8x to 14x + 1. / Your problem should look like: 21 = 14x + 1.
Eighth, subtract 1 from both sides. / Your problem should look like: 21 - 1 = 14x.
Ninth, simplify 21 - 1 to 20. / Your problem should look like: 20 = 14x.
Tenth, divide both sides by 14. / Your problem should look like:
= x.
Eleventh, simplify to 
. / Your problem should look like: = x.
Twelfth, switch sides. / Your problem should look like: x = which is your answer.
