Question 1033940: A pyramid has all sides that are equilateral triangle's if the surface area of the pyramid is 330 centimeters squared what is the slant height of the pyramid? Answer by sachi(548) (Show Source):
You can put this solution on YOUR website! A pyramid has all sides that are equilateral triangle's
so the surface area =330=3 x Area of equilateral area=3 X 3^(1/2)/4 X a^2
which gives sides of the eq. triangle = 12.11cm
the slant height of the pyramid= the sides of the eq. triangle=12.11 cm
