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. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area
One of the missing angles is 45degrees 64+71=135 then subtract from 180 since it is a triangle. Then 64 are vertical angles with the one across from it which stays the same. The last angle would be 64+56=120 and 180-120=60 which would be the last angle. Hope this Helps... Juan
8 x 200
= 8 x 2 x 100
= 16 x 100
= 1,600

Answer:
$1,600
? + 8 = 11
Subtract 8 from both sides.
? = 3
HG = 8
? + 6 = 9
Subtract 6 from both sides.
? = 3
HI = 3
