3D SHAPES

Today we made 3D Shapes out of sticks. The shapes that I made were The cube , cuboid  and Square Pyramid. It was really fun!!! We got a formula for maths off  Mrs Roil it is : Faces + corners - 2 = Edges.
Square Pyramid: 5 faces , 8 Edges , 5 corners.
Cube: 6 Faces , 12 Edges , 8 Corners.
Cuboid: 6 Faces , 12 Edges , 8 Corners.
