1"x2"x3" blocks have those dimensions on one each of their three sides. They are usually precision ground and are used as leveling blocks or tiedown spacers on machine shop equipment such as milling machines. They could also be used anywhere it is desired to have precision spacers.

It is the same as trebles. Start with how many selections there are and then times by the next number in the sequence and times that by the next number. Then divide that number by 1x2x3. For example 5 selections 5x4x3 =120 / 1x2x3 =6 = 20 trebles in 5 selections. But because it is a reverse forcadt you need to then times that by 2
120. The numbers are factorials: 1, 1x2, 1x2x3, etc.

Factorial. n! = 1x2x3x4x.....x(n-2)x(n-1)xn. Examples: 3! = 1x2x3 = 6 7! = 1x2x3x4x5x6x7=5040

You can create five distinct rectangular prisms using 6 unit cubes. The possible dimensions are 1x1x6, 1x2x3, and their permutations, leading to the following combinations: 1x1x6, 1x2x3, and 2x3x1. Each combination can be arranged in different orientations, but the unique shapes remain limited to these configurations.
1,2 and 3 1+2+3 = 6 and 1x2x3= 6
1+2+3=6 1x2x3=6 123
6 = (1+2+3) 6 = (1x2x3)
