Summary Packing Parcels A math puzzle inspired in our daily life. Everyday we use mathematics to make all sorts of things in our lives, including packing parcels. Print Settings Printer: Bq Witbox Rafts: No Supports: No Resolution: 0.2mm Infill: 20% Notes: Filament: PLA, Print Speed: 60mm/s, Bed adhesive: hair spray Post-Printing Clear the holes with a small rasp. How I Designed This Step 1 - Draw Box 1 Write the code in OpenSCAD: difference(){ difference(){ cube([20,20,20], center=true); cylinder(h=20,r=3, center=true); } rotate([90,0,0])cylinder(h=20,r=3, center=true); rotate([0,90,0])cylinder(h=20,r=3, center=true); } Step 2 - Draw Box 2 Write the code in OpenSCAD: difference(){ difference(){ cube([40,40,20], center=true); cylinder(h=20,r=3, center=true); } rotate([90,0,0])cylinder(h=40,r=3, center=true); rotate([0,90,0])cylinder(h=40,r=3, center=true); } Step 3 - Draw Box 3 Write the code in OpenSCAD: difference(){ cube([66,66,66], center=true); translate([0,3,0])cube([63,63,63],center=true); } Step 4 - Draw the Stick Write the code in OpenSCAD: cube([100,1,3], center=false); translate([100,0,0])cube([1,3,3],center=false); Project: Packing Parcels Packing Parcels A math puzzle inspired in our daily life. Everyday we use mathematics to make all sorts of things in our lives, including packing parcels. Overview & Background This project gives me more knowledge about math and teaches students about geometry, volume, and area. Objectives At the end of this project, students will know more about: Geometry Volume Area And understand how they are related to each other for solving this type of puzzle. Audiences This project can be made by children with 14 plus years old. Subjects Math Skills learned Spacial thinking How to solve problems with math help Activity Teacher can present to the class a puzzle challenge where students have to fit 9 parcels into a box. Solution for the Puzzle This will be a future project that I made my first steps now. You can use Aurasma to view an augmented reality of this puzzle made by me. Physics and Chemistry Atoms and molecules are packed together to form solids, liquids, and gases. Particles in a solid are usually more tightly packed together. And in our daily life If you use salt to season food next time remember that all sodium chloride crystals are cube shape. Inside the crystal sodium ions and chloride ions are packed together. If you plan a trip and have to pack many things into a small car, you need to use the space efficiently. If you don’t, you may have to make an extra trip or buy a larger car! Solution for the puzzle This will be a future project that I made my first steps now. You can use Aurasma to view an augmented reality of this puzzle made by me. Preparation Have the files printed Have the trigger printed Have phones or tablets with Aurasma app installed to see the solution References The math is quite simple, so for now, no references Rubric & Assessment Most students will solve the puzzle in time. If you want to step up there is a small big detail, inside the box3 (red box) fit exactly the volume of 27 box1(the smaller one). This means that if you design pieces that all together reach 27 box 1 you can create your own pieces and challenges. Handouts & Assets You can download the trigger.png to see the solution with Aurasma
