NG Rathi Associates Senior Estimation Engineer Interview Questions and Answers

Rebar weight can be calculated by multiplying the volume of rebar by the density of steel.

• Calculate the volume of rebar by using the formula: Volume = (π * (Diameter/2)^2) * Length

• Determine the density of steel, typically around 7850 kg/m^3

• Multiply the volume of rebar by the density of steel to get the weight in kg

• For example, if the diameter of rebar is 12mm and length is 1m, the weight can be calculated as: Weight =

Volume can be calculated by multiplying the length, width, and height of an object.

• Volume = Length x Width x Height

• Make sure all measurements are in the same units (e.g. meters, feet)

• For example, to calculate the volume of a rectangular prism with length 5m, width 3m, and height 2m: Volume = 5m x 3m x 2m = 30 cubic meters
