. Any prism or cylinder (Figure 1-18)
,
volume = Bh = N1
lateral area = Q1
where 1 = length of an element or lateral edge
B = area of base
N = area of normal section
Q = perimeter of normal section
Hollow cylinder (right and circular)
volume = rch(R2 - r2) = nhb(D - b) = nhb(d + b) = rchbD' = rchb(R + r)
where h = altitude
r,R, (d,D) = inner and outer radii (diameters)
b = thickness = R - r
D' = mean diam = 1/2 (d + D) = D - b = d + b
Regular pyramid (Figure 1-19)
