1×36

1×36 is a notation used in several contexts with different meanings. In basic arithmetic, 1×36 denotes the product of the numbers 1 and 36, which equals 36. It also illustrates the identity property of multiplication: any number multiplied by 1 yields the same number. In linear algebra and data processing, 1×36 can describe a 1-by-36 matrix, i.e., a row vector with 36 elements.

In dimensions and materials, 1×36 commonly appears as a nominal size for boards or strips, indicating a cross-section of about 1 inch by 36 inches. However, “nominal” sizes are not exact; the actual dimensions for such a piece are typically smaller due to milling and finishing. For example, a nominal 1×36 board might measure roughly 0.75 inches thick by about 35.5 inches wide, with the length depending on the purchase. Wide boards of this proportion are relatively uncommon in standard lumber, but the 1-inch thickness is a familiar reference in some specialty decking, paneling, or trim products.

In other domains, 1×36 can appear as a dimension in drawings or manufacturing specifications, where the units (inches, millimeters, etc.) and orientation depend on the context. As with many dimensional notations, the exact meaning is defined by the conventions of the field and the accompanying units.
