I am thinking of a solid with six identical square faces. Name the solid, and say whether it is a prism or a pyramid.
I am thinking of a solid with one five-sided face, with five triangles rising to a point. Name the solid, and say whether it is a prism or a pyramid.
The diagram shows the net of a solid. Which solid folds from this net, and how many faces does it have?
How many faces (F), edges (E) and vertices (V) does a triangular prism have? Verify that F+V−E=2F+V-E=2F+V−E=2 (Euler's formula).
A solid has identical six-sided end faces joined by rectangles. Name the solid, and say whether it is a prism or a pyramid.
Consider a triangular prism. Write down the number of faces (F), edges (E) and vertices (V), and verify Euler's formula, F+V−E=2F+V-E=2F+V−E=2.
A solid has two identical pentagonal faces joined by rectangles. Name the solid, and say whether it is a prism or a pyramid.
The diagram shows the net of a solid. Name the solid this net folds into, and write down its number of faces.
Consider a pentagonal prism. Write down the number of faces (F), edges (E) and vertices (V), and verify Euler's formula, F+V−E=2F+V-E=2F+V−E=2.
Consider a cube. Write down the number of faces (F), edges (E) and vertices (V), and verify Euler's formula, F+V−E=2F+V-E=2F+V−E=2.
The diagram shows the net of a solid. Name the solid this net folds into, and explain what the rectangle forms.
How many faces (F), edges (E) and vertices (V) does a cube have? Verify that F+V−E=2F+V-E=2F+V−E=2 (Euler's formula).
