Answer:
294
Step-by-step explanation:
The area of one face of the cube would be 7 x 7 = 49 
Since there are 6 faces on a cube, the total surface area would therefore be 49 x 6 =

8. -39
Step-by-step explanation:
Answer:
B = 15.1°, C = 34.9°, c = 39.6
Step-by-step explanation:
law of sines
53/sin 130 = 18/sin B
sin B = .26; B = 15.1°
C = 180 - 15.1 - 130 = 34.9°
c/sin 34.9 = 53/sin 130
c = 39.6
