Abstract: An extension of result in [1] to two dimension is derived in this paper. The new numerical formula for double integral possesses the all advantage of Simpson's formula but the degree of accuracy is increased by two order than that of Simpson's formula.The numerical tests show that the new numerical formula of this paper is more efficient.

Key words: numerical integration, numerical approximation, error estimate
