GCSE Volume of a Prism (Swimming pool question)

geometry

enter image description here

Hi, looking please for any help in answering part a) of the attached question.

My attempt was the following:
Aim to use the formula for the volume of a prism.

Split the cross section into a 1.4m x 25m rectangle and then a trapezium with parallel sides of length 8m and 15m, base 1.6m. Multiply this by the length, 10m, to get 534m$^3$.

But how now does this help in answering the question? I feel like I may have missed something more obvious here. All help/solutions appreciated.

Thanks

What you need here is the volume of 1 litre of water. It so happens that $1l$ of water is $0.001m^3$.

If the pool takes $534m^3$ of water (I haven't checked your calculation), and $0.5m^3$ goes in per minute, I suppose that you can do the rest.

EDIT: You may wish to state your assumption about what the volume of $1l$ of water is.
