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!
Square root 64 = 8
26/3 = 8 2/3 = 8.66666
8 2/7 = 8. 2857
So the order is sqrt(64) 8 2/7 26/3 8.8 <<<<< Answer
X-3y because 8x+2x-9x is x

I believe that’s it,

1: B $3.85
2: C The rabbit; 14 miles per hour
3: C 2 1/2 miles
1. Reason: To find the price per gallon, all you need to do is divide 46.20 by 12 to get 3.85
2. Reason: To find which animal is faster all you have to do is subtract the greater number, which is the rabbit that travels 35 miles per hour from the smaller number which is the fox that travels 21 miles.
Subtract: 35-21= 14. So the rabbit is faster by 14 miles.
3. Reason: If Randy walks 1/2 mile in every 1/5 hour, to find the much he will walk in a hour you could count up:
1/2 mile = 1/5 hour
1 mile = 2/5 hour
1 1/2 mile = 3/5 hour
2 mile = 4/5 hour
2 1/2 mile = 1 hour
So, Randy will travel 2 1/2 miles in a hour.
