How do you solve surface area of a rectangular prisem?

Properties of a rectangular prism: * A rectangular prism has a total of 6 surfaces. * Because it is rectangular it will have 4 equal longer edges and 8 equal shorter edges, and so * It will have 4 rectangular faces and 2 square faces, therefore * Total surface area = 2 x square (end ) surface + 4 x rectangular (side) surfaces If we let x = shorter edges (breadth) & y = longer edges (length), and, as area = length x breadth, then * each end (a square surface) will have an area of x2 * each side (rectangular surface) will have an area of xy Thus: Total surface area of the rectangular prism = 2 x end area + 4 x side area = 2x2 + 4xy = 2x(x + 2y) Hope this nswers your question and explains how we arrive at the formula for calculating the total surface area of a rectangular prism.


What is the formula for getting the area of a rectangular aolid?

The area of a rectangular solid, also known as a rectangular prism, is calculated using the formula ( A = l \times w ), where ( l ) is the length and ( w ) is the width of the base. To find the total surface area, you would use the formula ( SA = 2(lw + lh + wh) ), where ( h ) is the height of the solid. This accounts for all six rectangular faces of the prism.

How do you find the perimeter and surface area of a rectangular solid?

Well it depends what your asking, if your just looking for the perimiter it would be length times 2 plus height times 2. Now if your looking for lateral surface area the formula would be length times height times 2 plus length times height times 2, heres a better look at the formula. perimiter (P) = L+L+W+W lateral surface area (LSA) = 2xLxH +2xWxH Now if your looking for total surface area (The total surface area of a rectangular solid includes the lateral suface area plus the area of the top and bottom) The formula would be. Total surface area (TSA)= 2xLxH + 2xWxH + 2xLxW W = Width L = Length h = Height Well I hope that helps Karp
