Linear feet is calculated by adding the lengths of points connected by straight lines. For example, the perimeter around a house can be measured in linear feet. Square feet measures area, and linear feet measures length.
Two areas that measure the same square feet can have different perimeters, hence differing values for linear feet, if they’re shaped differently. For example, a rectangle that measures 8 feet long and 2 feet wide has an area of 16 square feet (length x width) and a perimeter of 20 linear feet (2 x (length + width), while a square that measures 4 feet by 4 feet has the same area but a perimeter of 16 linear feet.

Full Answer >The weight of a steel bar is calculated depending on its shape. Its weight per cubic inch is 0.2904 pounds. The weight of a square bar in pounds per foot is calculated by multiplying 3.40 pounds by L squared, where L is the length of one of the sides.
Full Answer >When the gross weight and the net weight are known, the tare weight may be calculated by subtracting the net weight from the gross weight. Most containers should also have a plate stating their tare weight.
