The document provides various measurements in centimeters of lengths, widths, heights and areas. It contains measurements for nets of different 3D shapes including tetrahedrons, prisms and a hexagonal pyramid. The measurements are used to calculate surface areas and totals for each net. The overall totals calculated are 275cm^2 for a tetrahedron, 2944cm^2 and 1362cm^2 for different prisms, and 1536cm^2 for the hexagonal pyramid net.
