Area = 0.5*(sum of parallel sides)*height
You can't derive the volume from the surface area.
Area of a trapezoid: 0.5*(sum of parallel sides)*height
All you have given is a rectangle which I presume encloses the composite shape. It is impossible to give the area of the composite shape other than to say it is less than or equal to 8 sq units. To work out the area of a composite shape, split it up into areas which you can work out (eg squares and rectangles) and sum the area of all the area.
A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape).For example, figure ABCD is a composite figure as it consists of two basic figures. That is, a figure is formed by a rectangle and triangle as shown below.The area of a composite figure is calculated by dividing the composite figure into basic figures and then using the relevant area formula for each basic figure.Example 20Find the area of the following composite figure:Solution:The figure can be divided into a rectangle and triangle as shown below.So, the area of the composite figure is 216 cm2.
To work out the area of a composite shape, you will have to divide it into smaller figures.

There is no information on the shape of the area in question.

There is no single formula, unless you consider the following:Sum(Area of each part of the composite shape calculated according to its bus-formula).
mass moment of inertia is the property of the body to resist rotation about the given axis where as the area moment of inertia is the resistance to bending about the given axis
Not really. While there is nothing that would prevent a composite volcano from developing under an area where a pond happens to be, there is no pond big enough to contain a composite volcano. As soon as the volcano starts forming, the first significant eruption would probably fill in or blast away the pond.
