Geometry A rectangular piece of cardboard is 10 in. longer than it is wide. Squares
2 in. on a side are to be cut from each corner, and then the sides will be folded up to make an open box with a volume of 192 in $^{3} .$ Find the length and width of the piece of cardboard.

Key Concepts

Rectangular Geometry

This concept relates to understanding the properties of rectangles, including how the length and width relate when one dimension is defined in terms of the other. It involves the use of variables to represent dimensions and applying given relationships to formulate equations involving these dimensions.

Geometric Transformation from 2D to 3D

This concept involves converting a flat, two-dimensional shape into a three-dimensional form by altering its structure, such as cutting out sections and folding along edges. In many problems, such modifications change the dimensions of the original shape, leading to new lengths, widths, and heights that are used in further calculations.

Volume Calculation of an Open Box

This is the process of determining the amount of space inside a three-dimensional object, in this case, an open box. It is done by multiplying the dimensions of the modified base by the height of the box. Understanding this concept is crucial for setting up the volume equation to meet a specified condition.

Algebraic Modeling of Geometric Problems

This key idea involves translating the geometric conditions and transformations described in a problem into algebraic equations. It requires assigning variables, applying relationships between dimensions, and forming equations that can be solved to determine unknown values. This process is fundamental for solving real-world geometry problems by linking descriptions to precise mathematical statements.
