Your school is considering embarking on an irrigation project to supplement school finances through selling agricultural produce to the community, the school decides to build a rectangular tank with a square base side x meters. Given that the ideal surface area for an open tank is 75 square meters (75 CALA TASK
a). evaluate the height (h) of the water tank in terms of x,
b). determine the volume of the tank, given that it’s not closed on top
c). as x varies determine, its stationary value and prove that it is a maximum value for the volume.
d). The O level building students are to be engaged to build the tank. Given a 10 percent (10%) measurement error for the value of x can be tolerated. Find the corresponding percentage error of volume.
