Question 915715
v for value
A for area
w for quantity of water
{{{v=kAw}}} for a constant of proportionality, k


{{{k=v/(Aw)}}}
Using the known values which establish the value of k,
{{{k=51000/(375*200*20)}}}
{{{k=51/(375*4)}}}
{{{k=17/(125*4)}}}
{{{k=17/500}}}


Value formula, {{{highlight(v=(17/500)Aw)}}}


Value for the question, {{{v=(17/500)(200*400*10)}}};
Simplify v.
