$5.$ What is an approximation of the boundary work as the volume changes from $1f{t}^3$ to $2f{t}^3$ for the sty represented in Figure $1$ below?

a$.60\mathrm{.}0ft*lbf$

Answer

b$.108ft*lbf$

$108ft.$

c$.,0\mathrm{.}417ft*lbf$

d$.261ft*lbf$

e$.1\mathrm{.}81ft*bf$

G$.$S $(y_2+y_1)(x_2-x_1)$

$0\mathrm{.}5(6\mathrm{.}5+1\mathrm{.}60)(2-1)f{t}^3$
