Please answer the following question

If a box with a square cross section is to be sent by the postal service, there are restrictions on its size such that its volume is limited by V = x2(140 5x), where x is the length of each slcle of the cross section (in inches). (a) If V = 1.1x], find W10) and V{20). van) = in3 van) = in3 (b) For the problem to make physical sense, all dimensions of the box must be -Seleot a . Therefore, Selecl a and Se|eot Solve the second inequality in the statement above forx. What restrictions must be placed on x (the domain) so that the problem makes physical sense? Give the domain.
