Class 4 have made our own treasure chests. We used a net of a cuboid and folded it to make the correct shape. We had to cut  and fold the shape carefully. We know that a cuboid has 6 faces or surfaces. It also has 8 vertices and 12 edges. We counted these features on other 3D shapes and found these shapes in a walk around our school. we hope our treasure chests will be filled soon!
