Volume[reg]
gives the volume of the three-dimensional region reg.
Volume[{x1,…,xn},{s,smin,smax},{t,tmin,tmax},{u,umin,umax}]
gives the volume of the parametrized region whose Cartesian coordinates xi are functions of s, t, u.
Volume[{x1,…,xn},{s,smin,smax},{t,tmin,tmax},{u,umin,umax},chart]
interprets the xi as coordinates in the specified coordinate chart.
