1. - Since a cube is all the same lengths on all sides you would want to find the area of one of the sides. You would do this by multiplying 3.8 by 3.8.
3.8*3.8=14.44
Since you have six faces on a cube you want to multiply this by 6.
14.44*6=86.64
So your answer for 1. is 86.64 in^2 of glass
3. Same thing as number one. Find the face of one side:
1 1/3*1 1/3 is about 1.7777
Multiply this by the six faces.
1.7777*6 is about 10.66666
So your answer for 3. is about 10.666 (repeating) in^2
4. For this one, you want to follow the surface area formula for a cylinder. Which is - A=2πrh+2πr^2
When you put all your numbers in it would look like this:
2*3.14*2*22+2*3.14*2^2
Once you do that equation you will get 301.44
So that should be your answer 301.44 cm^2
Hope this helps!
Yes, 13x and 7x+6x are equivalent. When you simplify 7x+6x you get 13x.

Answer:
4.05 miles.
Step-by-step explanation:
See the attached diagram. (not in scale)
Let AB is the Clayton Road and its length is 2.35 miles and BC is the Wood Pike Road and it is 1.7 miles long.
So, the combined length of Clayton Road and Wood Pike Road is AC (= AB + BC)
So, the length of AC will be (2.35 +1.7) miles = 4.05 miles. (Answer)
Your answer would be A= $11+ j x (.50)
A= total which is based off of how many cups (j) you sell of OJ... plus the $11 you started with.
