1. The problem statement, all variables and given/known data

Use Riemann sum with c_{i}= i^{3}/n^{3}

f(x)= [tex]\sqrt[3]{x}[/tex] +12

from x=0 to x=18

n= 6 subintervals

Approximate the sum using Riemann's Sum

2. Relevant equations

[tex]\Sigma f(ci) \Delta[/tex] xi

is the equation for riemanns sum i think

3. The attempt at a solution

i tried plugging in stuff using that, but i must've done something wrong because the answer i got was 200 off the actual area under the curve...
