Q:

# What are length, width and height?

A:

Length, width and height are the measurements taken of a three-dimensional object. These measurements can then be multiplied together to find the object's total area.

Length is the longest extent of anything as measured from end to end. Width is the extent from side to side, breadth or wideness of an object. For example, if the floor of a racquetball court measures 20 feet by 40 feet, the length is 40 feet and the width is 20 feet.

A racquetball court is a three-dimensional area having length, width and height. Height is the distance upward from a given level to a fixed point. The height of the racquetball court would be measured from the floor of the court to the ceiling. In this case it's15 feet.

Perimeter and area are calculated from measured length, width and height. Perimeter, the distance around an object is found by multiplying length times width. Forty feet times 20 feet is 800 square feet. Area is calculated by multiplying length times width times height. Forty feet times 20 feet times 15 feet is 12,000 cubic feet.

Length, width and height can also be used individually to measure two-dimensional objects. For example, a coiled rope can be laid out straight and the length measured from end to end.

You can calculate acreage by measuring a plot of land's length and width, multiplying those two figures together to find square footage, then dividing that number by 43,560. For irregular parcels, try splitting measurements into smaller rectangles or other geometric shapes, or use specialized software.
