What is the standard size of a building block?
440mm x 100mm x 215mm
Blocks are produced in a broad range of sizes, but for general building work the most commonly used is referred to as a standard block and measures 440mm x 100mm x 215mm (see Figure 2). Usefully, this is the same length as two bricks and the height of three bricks with 10mm mortar joints.
How much RAM do I have Linux?
To see the total amount of physical RAM installed, you can run sudo lshw -c memory which will show you each individual bank of RAM you have installed, as well as the total size for the System Memory. This will likely presented as GiB value, which you can again multiply by 1024 to get the MiB value.
