Tube has 2 faces and 0 vertices
That shape is called a triangular prism. A prism is made of rectangles arranged in a tube with any 2D shape at the ends. This shape determines what kind of prism it is, you can get pentagonal, hexagonal, and many other types of prism.

At this angle the biggest "area" of the test tube is covered by the flame. Thus it heats up quickly and evenly. Also, by holding the test tube at 45 degrees away from you, you're less likely to be splashed by anything in the test tube boiling over.

I can't speak with any authority, BUT seems to me a cylinder can exist in one of three configurations which would effect the answer (a fixed length with two discrete ends--like a line segment, an infinite length with one fixed end--like a ray, and an infinite length with neither end fixed--like a line). Hence a cylinder has two faces (inside and outside), either zero vertices (if the tube is zero-ended) or infinite vertices (at infinitesimal degrees of rotation around the bends of the tube at the defined end or ends of the tube) (if the tube is single or double ended), and infinite edges (running longitudinally the length of the tube if there is one or two ends). I'm totally guessing as the the number of edges in the case of a zero ended cylinder, but I would have to say infinite there as well, and relying on a series of radially discrete but longitudinally non-discrete albeit perhaps imaginary point around the cylinder in the two extreme lengthwise directions of the cylinder.
Well it depends on who you ask. Some people say that where the face meets the side is called an edge, while others claim not. Decide on this description of a tube, a tube has 2 round faces and a round side connecting them (if you want a better desc. then look at that can of beans in your cabinet!)
Get a tube of Pringles potato chips and empty it. Stuff the tube with kitchen cleaning sponges or something and finally put a condom in. Put the condom edges around the tube edges so it wont slide off.
A rectangular tube.
Compact bone is found as a tube around long bones.
you tube videos Alternatively: If the cubes edges are 5cm long, then you can find: a) its total surface area (of the 6 square faces) = 5cmx5cmx6 = 150 square centimetres b) its volume by multiplying length by breadth by height = 5cm x 5cm x 5cm =125cc (cubic centimetres c) the total length of all of its edges, of which there are 12 measuring 5cm each = 12 x 5cm = 60cm

What tube
There are 287 tube stations
Along coral wall faces at depths of 40 to 80 feet
There are 23 in a average green tube :)
Under the hood, passenger side of firewall, below the lowest point of the HVAC box. You can feel the small tube that faces straight down with your fingers but it is very hard to see.
