    We can't answer this without more information on the shape you want. You could make a long skinny tank or a cubic tank to hold exactly the same amount.

    In any case, you should know that a litre is defined as 1000 cubic centimetres. A 50 litre fuel take would be 50000 cubic centimetres. If you made one in the shape of a cube, each side one have to be "cube root of 50000"= 36.8 centimeters, a little more than 1/3 of a metre, on each side. On the other hand, if you made the tank in the shape of a sphere, it would have to be about 11.5 cm in diameter.
    For a general rectangular tank, you need to find three convenient numbers whose product is 50000- those will be the dimensions in cm.
