<u>Answer:</u>
Below!
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- Length = Height = Width
- Volume = LHW = L³ = 64000
- Surface area = 6(area of a square)
<u>Part A Solution:</u>
- L³ = 64000
- ∛L³ = ∛64000
- => L = ∛40 x 40 x 40
- => L = 40 inches
Hence, the length is 40 inches.
<u>Part B Solution:</u>
We know that the length is 40 units. Since this is a cube, L must equal to W.
- => L² = 6(40 x 40)
- => L² = 6(1600)
- => 9600 square inches
Hence, the surface area is 9600 square inches.

Answer:
20 degrees
Step-by-step explanation:
Since angle B and angle A are both inscribed angles to the same arc, they must be equal. Therefore:
7x-8=5x
Subtract 5x from both sides:
2x-8=0
Add 8 to both sides:
2x=8
Divide both sides by 2:
x=4
Now, you can plug this back into the equation for angle B:
B=7(4)-8
B=28-8
B=20

Your answer would be about 40 miles
Answer:
18
Step-by-step explanation:
parallel lines cut by a transversal are proportional, thus we can set up a ratio to solve for the missing value
7/14 = 9/x
7x = 126
x = 18
