QUESTION 10 A cutting is to be formed on a straight section of a proposed road. The values of eight consecutive cross sectional areas taken at a constant horizontal distance interval of 20m are 325m², 398m², 456m², 580m², 634m², 546m², 447m² and 362m² respectively. Calculate the volume contained between the first and last cross section using : a. End areas method b. Prismoidal formula
