Rectangular cuboid - Surface Area

Patterns

Applicable neurons

• Plus (x + y)
• Multiple (x × y)
• constant x.x
• NOR
• Rounding to whole thousands of something
• [a, +∞)
• constant x.xx
• Get the last XY characters
• character }
• IfNull
• get month from date (yyyy-mm-dd)
• Convert date (yyyy-mm-dd) to year, month, day
