A rectangular tank with a square base, an open top, and a volume of 6912ft cubed is to be constructed of sheet steel. Find the dimensions of the tank that has the minimum surface area.
Let s be the length of one of the sides of the square base and let A be the surface area of the tank. Write the objective function. A=

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

step-by-step explanation:

left be aligning the decimal points is required to not required see the number of digits to the right
