Why do we measure area in feet squared or feet cubed?

Question

Why do we measure perimeter in ft, area in ft^2 (or feet squared), and volume in ft^3 (or feet cubed)? What does each mean within the strand of measurement?

Answer 1

the² or ³ stand for the number of dimensions.

Feet is the basic device for walking.

Used for going to a planet you miss is sometimes.

But thats non of my business.

Answer 2

Area is the product of two lengths (ft × ft) = ft²

Volume is the product of three lengths (ft × ft × ft) = ft³

Answer 3

Well, perimeter is measured in any unit of length.

Area is a square because there is an equivalent area that is a square with sides that are easily measured- even for a circle.

Area is measured by length times width.  If you make the area equivalent to a square, then the length and width is the same.  Any number multiplied by itself is "squared"

Volume is the came concept because volume is area times height.

Answer 4

We calculate area for a plane figure,ie.,2 dimensional. So it is product of length and breadth. Hence feet squared.

Same logic applicable for volume. here it is 3 dimensional. Product of length,breadth & height.

  

Answer 5

area is 2 dimensions and volume is 3, hence the exponents

Answer 6

Because someone are too lazy to learn about metric system.
