An equilateral triangle of sides 3 inch each is given. How many equilateral triangles of side 1 inch can be formed from it?

• since the combined area of all the small triangles will be equal to the area of the original triangle
  so.no. of triangle that can be formed=((sqrt(3)/4*)3*3)/((sqrt(3)/4)*1*1)=9

• volume of equilateral triangle = 1/2*bh (b base, h height)
  volume of 3 inch Eq tri =1/2*3*20598 = 1/2*1*.866*N(volume of 1 inch eq tri and N is no of 1 inch triangles9
  so ans is 9
