a rectangle or square
A net.A 2-dimensional pattern that you can fold to make a 3-dimensional figure is called a net.For instance, make a letter 'T' out of 6 squares. The vertical part of the T has 4 squares, and the horizontal part has 3 squares (one square is common to both) . This net can be folded to make a cube.
A pentagonal prism.
i need to make a 14 sided figure from straws and pipe cleaners
Using the Euler cahracteristic, these two items of information uniquely determine the number of faces for a simply connected polyhedron. That might help you make a three dimensional figure but you will need to be practised to recognise patterns in these numbers.
A net is a two-dimensional figure which can be folded into a three-dimensional figure. It's a little difficult to describe in words . . . To make a regular triangular prism, start with a rectangle, and divide it into three equal (narrow) rectangular strips. on the two ends of one of these strips, make equilateral triangles.
You can make four.
A rectangular prism that is 4 cubes by 2 cubes is made up of 8 cubes.
Yes, 81 cubes can be arranged in a flat pattern of 9 columns of 9 cubes.
Put all the cubes in a line.
