x - 4 = sr(29)
x = 4 +- sr(29)
Answer: Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces.

8 dollars per hour
Step-by-step explanation:
You make 92 a week
20 of that is from your allowance
