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, 64√3 = (√3/4) X a2 Or, a2 = 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
