Best ResponseYou've already chosen the best response.0Composite Trapezoid Rule: int(f(x),x=a..b)=((ba)/(2*n)) * (f(a)+2*sum(f(xj),j=1..n1)+f(b)) So for you, int(f(x),x=a..b)=15*(f(a)+2*f(a+30)+2*f(a+60)+...+f(b)) I assume your first and lest depth measurements are zero, so int(f(x),x=a..b)=30*(sum of all depth measurements)
