How to Calculate Cubic meter to square meter

Hi there,

i m doing a tank coating project. Given to me is the capacity of the tank that is 4000 cubic metres. Can i convert this capacity of cubic metres to square metres to get the internal surface area?

Consider the tank as a cylinderical vessel.

Now as Volume of Cylinder is 3.14 x r x r x h.

Therefore, 3.14xrxrxh = 4000 cc

Assume Height of the tank as 10 cm. i.e. h=10 cm

so, r = square root of (4000/3.14x10) = 11.32 cm

Now you are to find out Total Surface Area of the tank

i.e. 2x3.14xrxh + 4x3.14xr = (2x3.14x11.32x10) + (4x3.14x11.32)

So, Total Surface Area = 853 square cm.

Hope this should answer your query. If you need further assistance you can contact at

Only with additional information, if you look at the formulas for volume and surface area of various shapes, sphere, cube, rectangular solid, cylinder, you'll see that they have different ratios, a sphere having minimal area for it's volume, and a cube is lower ratio that a rectangular solid. If you know general shape and aspect ratio, even approximately, you can make a decent estimate. To be conservative, assume aspect ratio is more "long and skinny" than it really is, but don't go overboard, just round up.
