Calculate the volume and surface area of a truncated rectangular pyramid.
This calculator works for any measurement unit. For example, if you calculate inches, inches will have to be used in all the length fields, and the result of the areas will be square inches; the volume results in cubic inches and length measurements in the starting unit, inches.
V = H/6(Lw+Wl+2(lw+LW) B = LW+lw LA = 2((L+l)/2e+(W+w)/2f)) e = (W-w)²+H² f = (L-l)²+H² SA = LA+BA D =√L²+W² HL = √(D/2)²+H² a = sin-1(H/(D/2)) s/v = SA/V where V is the volume of the pyramid L the length of the base W the width of the base H the height of the pyramid BA the area of the base LA the lateral suface area SA the surface area of the pyramid D the base diagonal length HL the length of the hip (outside edge) a the angle of the hip s/v is the surface area to volume ratio
