## lili.gallegos one year ago How do you find minimum surface area of an open-top, square based, rectangular metal tank that will have a volume of 61 ft^3 ?

how do we define surface area for the tank? outside, or is inside included?

2. amistre64

assuming it just means the outside, how would you propose we setup a formula for finding the volume and surface area of the tank to start with?

You can use this online calculator to determine the surface area. This calculator is very easy to understand and use. http://www.acalculator.com/volume-conversion-calculator.html

The squares width for a minimum surface area for a volume of 61 ft^3 is:$w\to \sqrt[3]{122}$ or 4.95968 to the nearest 0.00001 ft^3. Refer to the attached file.
