You mean a rectangular prism? Like a block of lego? Then you just need to work out the surface area of the four sides, which will be two pairs of identical rectangles. So; ((L*W)+(W*D))*2 L ______|______ / /| /____________/ |-D | | | | | / |____________|/ \ W
If you mean a rectangular cuboid then they work out as follows:- Volume: 4.2*4*9 = 151.2 cubic cm Surface area: 2(4*4.2)+2(4.2*9)+2(4*9) = 181.2 square cm
A prism is a three-dimensional solid with two parallel bases, or faces, that are congruent.[1] The shape of the base determines what type of prism you have, such as a rectangular or triangular prism. Because it is a 3D shape, finding the volume (space inside) of a prism is a common task; however, sometimes you will need to find the height of a prism. Finding the height is possible if you have enough information already given: either the volume, or the surface area and perimeter of the base. The formulas described in these methods can work for prisms with bases of any shape, provided you know the formula for finding the area of that shape.
The area of a sphere is equal to its circumference times its diameter.There are a variety of ways to work out this formula, most of them involving calculus.(See the links for the volume of a sphere).
It would help if the question was less obscure. What do you mean by "work"? How the surface area affects chemical processes (for example the surface area of catalysts), or diffusion, or surface areas and friction?
Solar panels are typically rectangular in shape because it allows them to efficiently collect sunlight regardless of the sun's position in the sky. A rectangle shape provides a good balance between maximizing surface area for sunlight absorption and minimizing wasted space. This shape also makes it easier to install and connect multiple solar panels together in a uniform array.
To work out the area of the rectangular faces, you need to multiply the length by the width. You then need to multiply that answer by 3 (because there are 3 rectangular faces).To work out the area of the triangular faces, multiply the base of the triangle by the height and divide the answer by 2 (to find the area of one triangle). You then need to multiply it by 2 again because there are 2 triangular faces.Important: The height of a triangle is the distance from the top corner of the triangle down to the base (so that it meets the base at 90 degrees)You then need to add the total surface area of the rectangular faces to the surface area of the triangular faces to get the total surface area of the entire prism.(sorry for the essay :])
If the room is rectangular, multiply the the lengths of the walls. If the shape is not rectangular, you will need to break it up into rectangles or squares. Draw it out on paper and break it up into smaller parts whose area you can find.

You work both out from measurements of the shape and the relevant formulae.
If you mean a rectangular cuboid then they work out as follows:- Volume: 4.2*4*9 = 151.2 cubic cm Surface area: 2(4*4.2)+2(4.2*9)+2(4*9) = 181.2 square cm
Rectangular Solid Volume = Length X Width X Height V = lwh. Surface = 2lw + 2lh
The best shape for floating is generally a shape that is stable in water, such as a wide and flat shape like a paddle or a raft. This shape allows for better weight distribution and balance on the water surface. Square or rectangular shapes also work well for floating objects.

To work out the area of a composite shape, you will have to divide it into smaller figures.
The area of a sphere is equal to its circumference times its diameter.There are a variety of ways to work out this formula, most of them involving calculus.(See the links for the volume of a sphere).
The answer depends on what you wish to work out: the angles, height, surface area, volume. Also, you need more information: the vertical or inclined height and whether or not the pyramid is a right pyramid.
