Geometry
Rectangle Perimeter Calculator
Calculates the total boundary length of a rectangle from its length and width using P = 2·(length + width). Use it for fencing a yard, framing a picture, ordering molding, or any project that needs the distance around a rectangular space.
Geometry
Rectangular Prism Volume Calculator
Calculate the volume of any rectangular prism or box by entering its length, width, and height. Handy for shipping estimates, room capacity planning, aquarium sizing, and material quantity calculations.
