  • Labeling of the Layers:
  • What To Do:
    • How To Find Angles of the Trapezoidal Block:
  • 1) Measure the distance formed between the center of the igloo to the edge of the layer (b)
  • 2) Measure the Height that forms perpendicular with Base (h)
  • 3) Solve the angle of the that specific angle of the ramp (theta)
    • Arctangent( Height / Base) = angle of the trapezoidal block (in degrees)
  • Determining the Dimensions of the Block (Circular Layer):
    • 1) Measure the Radius of specific layer
    • 2) Calculate its Circumference ( C = 2 x pi x radius)
    • 3) Divide it by measured external length of a block
    • 4) If the number of the blocks match with the calculation, then igloo's layer can be formed accurately without any shortage of materials
  • Determining the Dimensions of the Block (Vertical/Height):
  • 1) Measure the height of the igloo as a whole
  • 2) Using the proportions, calculate the 'X' for each layer's specific block
    • Make sure the blocks are positioned on top of each other
  • 3) Set Base Layer's block to be 13/5 of the igloo's height
  • 4) Set Second and Third Layers' blocks to be 52/15 of the igloo's height
  • 5) Set Fourth and Fifth Layers' blocks to be 1/7 of the igloo's height
  • 6) Set Sixth Layer's blocks to be 1/8 of the igloo's height
  • 7) The Roof should be height of the igloo as a whole
  • Calculating the Ramp:
  • 1) The length should be the circumference of the layer's circle(X)
  • 2) Measure the Height that forms perpendicular with the dashed lines (Y)
  • 3) Solve the angle of the that specific angle of the ramp (theta)
    • Arctangent( Height / Base) = angle of the trapezoidal block (in degrees)
  • If the Igloo is built correctly:
    • The angle of the blocks in that particular layer should have an increasing trend from lowest to highest degrees
    • The Base is the radius of that specific radius; in other words, it should be the constant
    • Height should increase from lowest block to tallest block

What Not To Do

  • Presenting the Igloo into single equation:
    • y = -ax^2 + b; x = from a vertical point of view, the block number; b = height of the igloo
  • Problems Regarding Single Equation:
    • Inaccurate display = it doesn't necessarily show every single block in the 3-Dimensional plain
    • Symmetrically, the length of the block doesn't equal to each other side's block
    • Symmetrically, the height should be similar, if not the same, because of quadratic's concept. However, that's not true for the spiral igloo
  • Calculating the Volume:
    • Integrate 2pix(-ax^2 + b)dx [0, radius of one layer]
      • This doesn't answer the question...
      • Don't act smart by calculating unnecessary quantity or value if it doesn't calculate the shape of the block or the ramp of an igloo
