The flowerpot shown in the sketch has a uniform thickness of 3in. and is 1ft high. Find the amount of material necessary to construct 1000 such pots. (Neglect the drain in the bottom)
What I did is get the volume of the bigger frustum which results to:
V = [h(18^2 + 12^2 + sqrt (18 * 12))]/3
V = 1930.79 cu. in
I don't know now the next step...
the answer should be 1098 cu. ft.
Help please THANKS!
