amy stores the baseball she first hit a home run with in a cube shaped glass display box that has a width of 3.8 in.
how much glass is used to make the display box?
bennett displays his basketball jersey in a rectangular prism shaped glass case. the case has a length of 18 in, a width of 3.5 in. and a height of 25.5 in.
how much glass is used to make the case?
paul cuts apples into cubes with a height of 1 1/3 in. he then coats the apples in caramel.
how much area is covered in caramel?
tammy buys a cylindrical shaped document holder to keep her diploma. the holder has a radius of 2 cm and a height of 22 cm. the holder is made entirely of plastic.
how much plastic is used to make the document holder, rounded to the nearest hundredth? (use 3.14 for pi.)

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
