Answer:
294 cm^2
Step-by-step explanation:
length of the cube is 7cm each side
S.A = 2(7 * 7) + 2( 7 * 7) + 2( 7 * 7)
= 294 cm^2
All angles in a triangle = 180. SO we can make an equation to find y:
79+37+y=180
116+y=180 (combine like terms)
y=64 (subtract the 116)
Answer:
in decimal form it is 8.25
