Surface area of cuboid
4 days till exams and counting down - nerves shattered already!
A closed cuboid with rectangular base of width xcm. Length of base is twice the width and the volumn is 1944cm^3. The surface area of the cuboid is S cm^2.
a) Show that S = 4x^2 + 5832x^-1.
b) Given that x can vary, find the value of x that makes the surface area a minimum.
c) Find the minimum value of the surface area.
Going round in circles with this one. Or, going round in cuboids. ha ha
I kill me!
I have to say, that was a bit more than I expected. But, I worked my way through it and understand fully, now.
Thank you so much.(Bow)
