From a rectangular sheet measuring
175mmby
75mm, equal squares of side
xare cut from each of the four corners. The remaining flaps are then folded upwards to form an open box. a) Write an expression for the volume
(V)of the box in terms of
x. Fully expand all brackets
V=,m^(3)2 marks Unanswered b) Find the value of
xthat gives the maximum volume and give your answer to 2 decimal places.
x_(max)=,mmCalculate the volume to the nearest
mm^(3).
V_(max)=◻m^(3)
