Question

Are the two figures similar? (If yes, find the similarity ratio)

  1. Yes; 3    
  2. Yes; fraction numerator 3 over denominator 10 end fraction    
  3. Yes; fraction numerator 3 over denominator 5 end fraction    
  4. No    

hintHint:

Two figures are said to be similar if they are the same shape.

The correct answer is: Yes; fraction numerator 3 over denominator 10 end fraction


    Length = fraction numerator 24 over denominator 80 end fraction equals fraction numerator 3 over denominator 10 end fraction
    Width = fraction numerator 18 over denominator 60 end fraction equals fraction numerator 3 over denominator 10 end fraction
    Height = fraction numerator 12 over denominator 40 end fraction equals fraction numerator 3 over denominator 10 end fraction
    They are similar because the ratios of corresponding linear measures are all equal.
    Hence, the correct option is B.

    In geometry, a cuboid is a hexahedron, a six-faced solid. Its faces are quadrilaterals. Cuboid means "like a cube", in the sense that by adjusting the length of the edges or the angles between edges and faces a cuboid can be transformed into a cube.
