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?
