Chapter 6.6, Problem 269E

For the following exercises, determine whether the statements are true or false.

269. If surface $\text{S}$ is given by $\{(x,y,z):0\le x\le 1,0\le y\le 1,z=10\}$ , then ${\displaystyle {\iint }_{S}f(x,y,z)dS={\displaystyle \underset{0}{\overset{1}{\int }}{\displaystyle \underset{0}{\overset{1}{\int }}f(x,y,10)dxdy}}}$ .
