What is the surface area formula for a rectangular solid?
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
What is the volume and surface area of the rectangular that's 4.2 cm 4cm and 9cm?
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
How do I find the slant height of a rectangular prism?
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.
How do you work out the surface area of a sphere 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).
How does surface area work?
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?
How do you work out the surface area for a triangular prism?
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 :])
How do you work out total area of a room?
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.

How do you figure surface area to volume ratio?
You work both out from measurements of the shape and the relevant formulae.
Why are solar solar panels rectangle?
Most solar panels are rectangular in shape. The main reason for this is to be able to get the best use of an area. There are solar panels that are in other shapes also. They don't have to be rectangular to work.

How do l work out the area of a rectangle?
Rectangular Solid Volume = Length X Width X Height V = lwh. Surface = 2lw + 2lh

How do you work out the area of a composite shape?
To work out the area of a composite shape, you will have to divide it into smaller figures.

How do you work out the trigonometry of a rectangular based pyramid?
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.
