Question
A pyramid has a square base with a height of 12 cm. Each
of the pyramid's faces is an equilateral triangle, and the area of each face is 64ā3 cmĀ². Find the volume of the pyramid.Solution
Length of each side of the base of the pyramid = Length of base of each triangular face Let the length of base of each triangular face be 'a' cm. So, 64ā3 = (ā3/4) X a2 Or, a2Ā = 256 So, a = 16 {Since, length of side cannot be negative} So, area of base of the pyramid = 16 X 16 = 256 cm2 So, volume of pyramid = 256 X 12 X (1/3) = 1024 cm3
