You need to know the shape.
Then, depending on the shape there are various measures that you need. For example, if the shape is a sphere, all you need to know is its radius. But if you have its diameter or equatorial circumference or volume, that will enable you to calculate the radius and so the surface area.
For a pyramid, you need to know the area of the base and the perpendicular height. But, the slant height, together with some other measures, will suffice.

Why do cells need a large surface area?
pendu vhale
Which of the following is a major cause of the size limits for certain types of cells?
The major cause of size limits for cells is the surface area to volume ratio. As a cell grows, its volume increases faster than its surface area, leading to difficulty in exchanging nutrients and wastes efficiently. This can compromise the cell's functions and survival.
