               When the prepared graph is examined, it is seen that the two peak values
            included in the training data set cannot be estimated with sufficient accuracy
            in the model of both methods. In addition, it is observed that the estimated
            surface area values in the verification and test data sets are close to the actual
            surface area values. The surface area obtained from the prediction models
            and the actual surface area were compared by preparing scatter graphs for
            training, verification and test data sets respectively (Figure 8).
