Final answer:
The missing shape on the net of a cuboid is typically a rectangle that matches the dimensions of one of the other rectangles represented in the net. Each face of a cuboid is a rectangle and opposite faces are identical.
Step-by-step explanation:
The student's question pertains to identifying a missing shape on the net of a cuboid. A cuboid is a 3-dimensional figure with six rectangular faces. When creating a net for a cuboid, you unfold it into a 2-dimensional shape that includes all of its faces. If a shape is missing from the net, it would typically be a rectangle that matches one of the other rectangles already present in the net, as each pair of opposite faces in a cuboid are identical.
To determine the missing shape on a cuboid net, you have to look at the unfolded faces and identify which rectangle is not repeated. The missing rectangle would have dimensions corresponding to the length and width or width and height or height and length (depending on which face is missing) of the cuboid.
