2. Wide English abbreviation: W (width)

3. Gao Yingwen abbreviation: H (high)

The definition of the length, width and height of a cuboid is controversial. Some people think that length is not necessarily longer than width, while others think that length is longer than width. There are roughly the following views:

Length and width of the front: according to the placement position, the horizontal side of the front is the length of a cuboid, the width of the side pointing to the observer, and the height of the upper and lower sides.

Length, width and short: when the cuboid is placed in a fixed position, we are used to calling the longer side in the bottom surface as long, the shorter side as wide and the side perpendicular to the bottom surface as high. ?

Length and width: according to the placement position, the side height in the up and down direction, the two sides adjacent to the bottom surface, if one side is considered to be long, the other side is wide. ?

Extended data

Let the length, width and height of a cuboid be a, b and c respectively, then its surface area is S = (ab+bc+ca)×2, which is also equal to 2ab+2bc+2ca, 2 (AB+BC+CA);

Formula: the surface area of a cuboid = length× width×2+width× height× 2+length× height× 2, or: the surface area of a cuboid = (length× width+width× height+length× height) × 2.

Volume of cuboid

Cuboid volume = length× width× height.
