The surface area of the 3-D figure will be the total of the areas of the 2-D figures.
Area is a measure of the extent of a shape in two dimensional space.
the difference between a two dimensional shape and and a solid is that a two dimensional shape is plane and a solid you can see the whole shape a the inside.
Area is the measure of a two-dimensional space enclosed by a shape, and surface area is the sum of all the areas of the faces of a three-dimensional solid.
If a shape is two dimensional it has NO volume - volume is an attribute of THREE dimensional shapes.If you meant the AREA of an irregular two dimensional shape, then divided it up into areas which are not irregular and so you can calculates them, and sum the areas of these non-irregular shapes.If you meant the volume of an irregular THREE dimensional shape, then a similar process can be followed by dividing it up into three dimensional shapes you can can calculate the volume of and summing them, though if it is an irregular object that you are physically holding, then you can find its volume by finding the increase in volume of a liquid (In a regular container) when the object is submerged into that liquid.
The inside of a two-dimensional shape is called its interior.
The surface area of the 3-D figure will be the total of the areas of the 2-D figures.
Area is a measure of the extent of a shape in two dimensional space.
area is labelled in square units because, area is a two dimensional quality (LW) and a square is the simplest two dimensional shape to express area in.

Area is the measure of a two-dimensional space enclosed by a shape, and surface area is the sum of all the areas of the faces of a three-dimensional solid.
To measure the area of an arbitrary two dimensional shape you will use a planimeter. To measure an area you could also just use a simple ruler depending on how big the area is.
You need to find the area of each two dimensional surface on the figure. Do you have a specific figure in mind?
