what would be a two-dimensional aspect of a cardboard box? what customary unit would you use and what metric unit would you use?

Answer 1

The plane objects are two-dimensional objects because the position of their any point is given by two coordinate numbers. If we ignore the thickness for a thin cardboard, each of six facets of the box is a two-dimensional rectangle. The rectangle is described by the lengths of two adjacent sides. They are often called the length and width of rectangle.

Length and width could be measured in meters or inches. To calculate the surface are of the rectangle you multiply the length and the width.

Answer 2

Probably the most commonly used two-dimensional mesurement is the surface area, which could be either total or lateral surface area. The total surface area can be viewed as the amount of wrapping paper needed to completely cover the box with no overlap. Or painting the entire outside of the box.

The lateral surface area excludes the top and the bottom. Think of decorating only the external sides of the box with paint or wrapping paper.

Square inches would be the mostly likely units of measurement in the British/American customary system.

Square centimeters would be the most likely units in the metric system. 2.54 centimeters is approximately one inch, for reference.
