A rectangle that is 5.4 in x 16.2 in
Step-by-step explanation:
As the container is lying on its side, and the scanner scans from the top, it means that scanner will get a 2D of cylinder where its length and width can be seen
First, whenever a cylinder is look at from one side, it will look like a rectangle.
As the cylinder is fitted with 3 balls along its length, the length of the rectangle will be equal to the sum of diameters of all three balls, that is 5.4+5.4+5.4 = 16.2 inches
As only one ball fits along the width of the, the width of the container will be equal to diameter of one ball, that is 5.4 inches
Hence, a rectangle will formed, with the dimensions of 5.4 × 16.2 in
