You really need to know the shape: sphere, cylinder, cube, etc as the ratio of area/volume depends on shape.
However, it is a cube, each side is the cube root of 1133 m³, or 10.43 m, and it has six faces which are the square of the this dimension, or about 652 m²
However, if it is a long skinny shape rather than a compact shape, the area will be more.
