SurfaceArea

SurfaceArea[reg]

gives the surface area of the three-dimensional region reg.

SurfaceArea[{x1,,xn},{s,smin,ssmax},{t,tmin,tmax},{u,umin,umax}]

gives the surface area of the parametrized region whose Cartesian coordinates xi are functions of s, t, u.

SurfaceArea[{x1,,xn},{s,smin,ssmax},{t,tmin,tmax},{u,umin,umax},chart]

interprets the xi as coordinates in the specified coordinate chart.
