Add more information <span />
The surface area is the area of the outside of a 3D shape for example, let’s say you have a cube, a cube has 6 sides, so you have to find the area of each side and then add it up, since it’s a cube you would technically have to find the area of one side and then just multiply it by 6, that would be the easiest way to do it
Hope I helped!
Answer:
x = 3, y = 6
Step-by-step explanation:
In the figure attached,
If ΔADE and ΔABC are similar triangles, their corresponding sides will be in the same ratio.
By this property,
3x = 2x + 3
3x - 2x = 3
x = 3
Similarly, 
y = 
y = 6
Ok the formula for this is 2(lw +hw+hL)
2(30+35+42)=2(107)=214 square feet
