Below is a net for a tetrahedron. If each equilateral triangle has sides of length 5 cm, what is the surface area of the tetrahedron? Note: Those little extra parts are tabs that help you to tape it together - don't include those in your calculations. What amount of paper (area) would you need to make a net for the cube with an edge length of 7 cm? Note: Show your net, and ignore any paper needed for tabs. Below is a net for a tetrahedron.
