Powerful 200 mW Red laser light

Orion is one of the most recognized brands providing high quality product at really affordable price.  Laser light is one of the Orion's finest products. Laser lights are available in various colors like red, green, blue etc. And Red laser light is gaining popularity as a toy and as a handy tool for everyone on their workplace as well. I am here to discuss the positive and negative points of the Orion Red laser light.

I am a teacher and as well as master of my 2 cats and 1 dog. Let's us start with the handiness I feel at school during lectures. It is really well designed, cylindrical in shape so it is very easy to hold in hand. You can use it to highlight main points or points where students should focus while studying.

Red laser light pen has power of at least 200 mW Laser Pointer and goes up to 250 mw. Common pointers available in the market are 5mw, and if you are a laser pen user so you can definitely understand the strength it has got. It is very helpful when you are in a dark room, once you open it, you can see almost every part of the room.

If you will turn it to sky, you will feel like it has never ending way. Even if you are expecting heavy clouds, you can easily look dark beam in the sky.

I use red laser light for my cats and dog as well. It is the greatest toy I have ever got for my pets. They are always ready to play with this red laser light. My pets try their best to chase and catch it, but they cannot, so they are curious to catch it and see, what it really is.

However, there are some precautions every laser user should adopt. The power this laser has got is ultimate and has the ability to leave your eyes damaged if projected in. So, it is a strict instruction to avoid emitting this laser in anyone's eye, no matter it is your pet or home mate. Stay safe!

To conclude, I would say, this is a real helper when you want a simple solution for your work place where you give presentations, or alike. And if you are at home so it is a great toy for your pets. The only thing, as I mentioned above, avoid projecting it in eyes. Keep it away from kids, and that is it, you have the best red laser light pointer around in your hand. So, in the end I am honored to pay it 5/5.

A cube has the dimension of 3x4x5. It is colored with three different colors namely red, green and black paint

A cube has the dimension of 3x4x5. It is colored with three different colors namely red, green and black painted on opposite corners of the cube. The cube is cut into 78 smaller cubes. 73 of them are smaller and 5 are bigger, but they have equal dimensions. Now, you need to calculate no. of cubes painted with red color, no. of cubes painted on three sides, no. of cubes painted on two sides, no. of cubes painted on one sides and no. of cubes painted without any painting.

For the pedants, let us say:

1. It is a rectangular prism.

2. Opposite faces are painted the same color.

3. The prism is cut into 73 equal-sized cubes plus 5 larger but also equal-sized cubes.

This seems like a really interesting problem. Wish I knew how to tackle it!

With some faddling about on paper, I got a good match for the cube sizes, with the smaller ones being 0.9 per side and the larger 1.107 per side (23% larger).

73 x 0.9^3 + 5 x 1.107^3 = 59.99999 = 3x4x5 = 60

This seems too close a match to be accidental, but is it physically possible to cut the prism into 78 cubes of the calculated sizes? That would seem to be important, but I don't see that it can be done!

So either I have the sizes wrong, or the sizes aren't important, and it is just the idea that the cutting that can be done that is important.

But it seems obvious that we have to know the disposition of each smaller cube (is it internal? in the corner? on an edge? on a face? totally internal?) to know how many faces are painted. So - what to do?
