  • 1. Unit 2 Project SurfaceArea and VolumeContainer Project DesignBy Shivank 8B Algeo Lemos
  • 2. Steps 1 : Adressing the problemThe purpose of this project is to build an efficient containerfor the hot wheels model car below. To do so I will build thecontainer and calculate the volume to surface area ratio tosee if it is efficient. and calculate the volume of thecontainer.
  • 3. Step 2: Build the container for theobject.
  • 4. Step 3: Take measurement of the net in order toestimate the volume and surface area of object
  • 5. Step 4: Calculate the volume andsurface area of the containerThe volume of an object is the amount of spaceinside the object measured in cm3.Volume= Height x width x length. Volume = 5 x 15.8 x 8 = 632cm3
  • 6. Finding surface area!The surface area of an object in the amount ofspace of the outside surface areas.side A = length x widthside B = length x widthtop = length x widthbottom = length x widthend A = length x widthend B = length x width15.8 x 8 x 2 + 5 x 8 x 2 + 15.8 x 5x 2= 490.8cm2
  • 7. Step 5: Calculate the surface area tovolume ratioThe efficiency of my container is based on thesurface area to volume ratio. The lower theratio the more efficient my container is. If Icompare my container to the blue cubicdecimeter that had a ration of .06 cm2/cm2, it isnot quite as efficient. I did not use up as muchspace inside the container as I should have. Icould have made it a bit smaller and wouldhave been more efficient. My container=Surface area/ Volume ratio= 490.8cm2/623cm3=0.79
  • 8. Analyzing my container!My container is enviromentally useful becauseas you know it can be kept in a shelf. Thestructure of my container is a rectangular prismtherefore it doesnt waste space for an item tofit in. I think if a company would examine mycontainer they would want build the same waysas I did.
