Answer:
726 in²
Step-by-step explanation:
The surface area of a cube is the area of each side of the cube multiplied by 6 (since the cube has 6 sides).
To know what is the area of each side, the formula is A= l² where l is the length. Therefore we would have that the area is 11²=121.
Now we are going to multiply this number by 6 to find the surface area, SA = 121 x 6 = 726 in²
Answer:307.2222 or just 307
62 +62 = 124
360 - 124 = 176
176/2 = 88
BED = 88 degrees
