The lower base of the frustum shown in the figure is a square 8ft on each side. The upper base is a square 4ft on each side. In the altitude is 6ft, find the slant height
The answer is D 6.32 S= the slant Height Then we need to get the apothem of the lower and upper base S^2 = (apothem of the lower base - apothem of the upper base)^2 + (height)^2 and they would be like this: apothem of the lower base = 8 / 2*tan(90/2) = 4 apothem of the upper base = 4 / 2*tan(90/2) = 2 S^2 = (4 - 2)^2 + (6)^2 S^2 = 2^2 + 6^2 S^2 = 4 + 36 S^2 = 40 S = 6.32
