Let E be the solid tetrahedron with vertices (0,0,0), (0,0,3), (0,2,0), and (4,0,0) where all
measurements are in metres. Suppose it has uniform density of 1 kilogram per cubic
metre. Determine the y coordinate of the centre of mass by evaluating the triple integral
y
Hints: Determine the limits of integration first. Make sure the limits correspond to a
tetrahedron and not a rectangular prism. Some of the integrals can get messy - in order to
keep them simpler you can try using the reverse chain rule rather than expanding
expressions.
