Chapter 3: Basic Geometrical Calculations ( Volume, Surface Area, and Weight Calculations in Estimation and Costing)
Abstract : In estimation and costing, basic geometrical calculations like area, perimeter, and volume are crucial for accurately determining material quantities and costs, which are then used to calculate the overall project budget. Key Geometric Calculations & Their Applications: Area: Rectangle: Area = Length x Width Square: Area = Side x Side Triangle: Area = 0.5 x Base x Height Circle: Area = π x Radius² Application: Estimating the quantity of materials like flooring, roofing, or wall coverings. Perimeter: Rectangle: Perimeter = 2 x (Length + Width) Square: Perimeter = 4 x Side Circle: Circumference = 2 x π x Radius Application: Calculating the length of fencing, skirting, or other linear materials. Volume: Cuboid: Volume = Length x Width x Height Cylinder: Volume = π x Radius² x Height Application: De...
