Investigating 3D shapes
Posted on November 20, 2014 | By cbutlerwoolsery
Some children in Ashmansworthy class were investigating Euler’s Law which states: For any 3D shape, the number of edges is always 2 less than the sum of the vertices and faces.
After investigating shapes such as cubes, square based pyramids and prisms, the children made their own more complex shapes to prove whether this law still was true.
