The circumference of a rectangle is two (length+width) X2.

Rectangular volume = length x width x height

Rectangular surface area = (length× width+length× height+width× height) x2

The total length of a rectangular side is 2 (length 10 width 10 height) x4.

Rectangular volume, two lengths x height x width

Square area, two sides long x sides long.

Square circumference, two sides length ⅹ 4

Square surface area, bisection length x bisection length x6

Square volume = side length x side length

Sum of sides of a square = side length Xl2

Two sides of a square volume are x sides.
