# Solving for Volume Using Multiple Integration

This is a past exam question.

Please help me understand how to go about questions a and b. I think I need some kind of double integral or something?

Systems Engineering B

The shape of the hull of a small barge of width w, length l and depth d, can be approximated by the multivariable function f(x,y), where:

(a) Show via multiple integration that the volume V of the hull is given by the following expression:

(b) If the mass of the barge is 100 tonnes, and its sides must clear the water by at least 1 m to safeguard against sinking, what is the maximum payload of the vessel, to the nearest 100 tonnes?

Vessel dimensions: w=6m

l=20m

d=9m
