I assume your container has a shape of a box.
We need to know the third dimension of your container to answer the question. Were those 4 and 8 feet width and height? We need also depth.
Knowing the three dimensions, the calculation is simple. You multiply all the three together to get the capacity of the container in cubic feet. Then you can convert the value from cubic feet to gallons here:
