Question 1061998: Part one,
what are the dimensions of the smallest rectangular prism that will hold three golf balls, each golf balls has the diameter of 42mm.
Part two
what are the dimensions of the smallest cylinder that will hold three golf balls, each golf ball has the diameter of 42mm.
Part three
find the surface are of the prism in part a) and the cylinder in part b) which container requires less materials.

You can put this solution on YOUR website! Part 1:
42*3 = 126mm is the length of the box
The sides are 42 x 42
-.-.-.-.-.-.-.-.-.-.-.
Part 2:
42*Pi is the circumference of the cylinder and 126 is the height (or length)
-.-.-.-.-.-.-.-.-.-.-.-.
Part 3 - Exterior surfaces only, if you need external and internal multiply times 2.
Box:
The box has 4 sides and 2 ends:
Sides (4 sides): 4(126*42) =
Ends (2 ends): 2(42*42) =
Multiply and add the products to get the total area of the rectangular prism
Cylinder:
(42*Pi)*126 outside surface of the cylinder (like I said, if you need internal and external just multiply times 2)
Ends (2 ends): 2 = 2 add this to the area of the cylinder above. Again, if you need the surface of both sides you need to multiply the result times 2.
