Answer:
Surface area of the cube = 
Step-by-step explanation:
Given shape in figure 1:
Cube with edge length = 5 cm
To find the surface area of the cube.
Solution:
The surface area of a cube is given by the formula:
where 
represents the length of the edges of the cube.
For the given cube 
Plugging in the formula to find the surface area of the cube.
∴ 
3x2−21x+3=0
Step 1: Use quadratic formula with a=3, b=-21, c=3.
x=−b±√b2−4ac2a
x=−(−21)±√(−21)2−4(3)(3)2(3)
x=21±√4056
x=72+32√5 or x=72+−32√5
answer
x=72+32√5 or x=72+−32√5
Parameterize this surface (call it 
) by
with 
and 
. Take the normal vector to to be
Then the area of is
Answer:
( -3/2 , 3)
Step-by-step explanation:
midpoint of segment: (x , y) : ((x + x') / 2 , (y + y') /2)
x = (3 + (-6)) / 2 = -3/2
y = (5 + 1) / 2 = 3
