Hi guys!
I thought it was [STRIKE]intergration[/STRIKE]integration, i think its differentiation.
Im having problems trying to figure out where to start with this question:
A rectangular tank with a square base x meters and height h meters is to be made from two different materials.
Material for the sides and top cost $65 per square meter, the material for the base cost $130 per square meter and the total cost is $5,000.
a) Show that the volume of the tank can be give by V= x²(5000-195x²/260x).
b) Determine the dimensions of the tank for maximum volume.
Now, from what I gather V= b X l X h or b²Xh. All valves seem to be a factor of $65 ie the darer material is twice the price of the cheaper material.
I just need someone to help me understand what I should be looking for, the square meter part throws me off.
Any help will be much appreciated,
