Question 773691
What is the volume (in L) of the pond? 

Volume (inL) = 2/3 x (length x width x average depth) x 1000
I don't know where that's from.
---------------
Length is 6m, height is 10m, average depth is 0.6m
If width = height, use the equation above ??  
Multiply the numbers.
(2/3)*6*10*0.6*1000
