What is an irregular solid?  (surface areas)?
826376
An irregular solid is like a stone, where you can not measure the sides. To get the volume of an irregular solid you can use water displacement.

The surface area of any prism equals the sum of the areas of its faces, which include the floor, roof and walls. Because the floor and the roof of a prism have the same shape, the surface area can always be found as follows:\ncall the 'floor' the 'base'. The height of the prism = 'H'.\nThe surface area of a prism = 2 × area of base  +  perimeter of base × H\n\nexamples:\n\nRectangular based prism:\nBase shape: Rectangle, length 'L' and width 'W'\nArea of base: L  × W\nPerimeter of base: 2(L+W)\nSurface area = 2LW + 2(L+W)H\n \nCircular based prism\nBase shape: Circle, radius 'R'\nArea of base: pR²\nPerimeter of base: 2pR\nSurface area = 2pR² + 2pRH\n\nTriangular based prism\nBase shape: Triangle: base 'b', height 'h', and sides S1, S2 and S3 \nArea of base: ½b×h\nPerimeter of base: S1+ S2 + S3\nSurface area = bh + (S1+ S2 + S3)H\n\nAs for lateral area of a cone , If r is the radius of the base, h is the altitude, and l is the length between the vertex and a point on the base circle \nlateral area pi rl=pi r x sq.root of r to the power 2 + sq.root of h to the power of 2\n or try this site- http://www.mathepower.com\n\nThe lateral area of a prism is the sum of the areas of the lateral faces (all the ...

Find the areas of all 6 faces of the rectangular solid by muliplying each one's width by length.  Then add them together for the total surface area.  To find volume, multiply length by width by height.  The ratio will be the total surface area divided by the volume (or expressed as a fraction the total surface area over the volume).

The area of a parallelogram is area = base x height. Now, drawing a diagonal of the parallelogram splits the shape into two congruent triangles. Therefore, each triangle will have an area equal to (1/2)base x height.\n\nThis is true for any triangle; that is, any triangle has a corresponding parallelogram associated with it, which can be cut in half.

The figure you are asking about is a pyramid.  If you think of the "traditional pyramid" it has a square base (which is a polygon), with 4 triangular sides that meet in a point at the top.  Yet in fact, a pyramid can have any polygon for a base.

The 13 Archimedean solids are the convex polyhedra that have a similar arrangement of nonintersecting regular convex polygons of two or more different types arranged in the same way about each vertex with all sides the same length (Cromwell 1997, pp. 91-92). \n\nThe Archimedean solids are distinguished by having very high symmetry, thus excluding solids belonging to a dihedral group of symmetries (e.g., the two infinite families of regular prisms and antiprisms), as well as the the elongated square gyrobicupola (because that surface's symmetry-breaking twist allows vertices "near the equator" and those "in the polar regions" to be distinguished; Cromwell 1997, p. 92). The Archimedean solids are sometimes also referred to as the semiregular polyhedra. \n\nThe Archimedean solids are illustrated below in alphabetical order (left to right, then continuing to the next row).

AREA\n\nPressure (symbol: p) is the force per unit area acting on a surface in a direction perpendicular to that surface. Mathematically:    P=F/A\nwhere:\np is the pressure \nF is the normal force \nA is the area.

To cacultate the surface area, you first need to know what shape it is.  follow this link for many different equations and find the one for your shape.

solid's particles are compact, while on liquids they are loose but gas' are the most loose (more distances with each other)

Let's look at the general case. It turns out that for even dimensional spheres, the ratio of the 'surface area' to the 'volume' of the next lower dimensional sphere is irrational in even dimensions and rational in odd dimensions. Your cases are just special cases of this general result.

This is pretty much a question of the definition you are using.\n\nIn a strict definition, conventional solids have a crystalline structure. Under this definition, glass is a supercooled, highly viscous liquid rather than a conventional (crystalline) solid. \n\nIn many ways, glass acts like a solid. Using that behaviour as a criterion, glass is a solid.

your question is not clear. describe positions of the objects.

Surface area of a sphere is = 4 pi r^2\nThis means that surface area of a sphere is equal to 4 times the biggest circle in the sphere Or 4 times the area of the circle swept by its radius or 4 times the area of the base of its hemisphere.For example if the radius of a sphere is 1 unit then its surface area is = 4 pi square units.When it is divided by 4 it is equal to the area of the base its hemisphere.ie. area of the base of its hemisphere is = pi square units.
