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.
