Dimensions of the Louvre

Spend 5 minutes in pairs writing down any questions you have about this project.What do we need to know to answer this question?

Things to consider: 1) What do the words “How much” actually mean? The volume of glass needed. 2) How many glass panes are there? 70 equilateral triangles, 603 rhombi 3) What are the dimensions of the panes of glass? No Info on this!!! Construction has a 35 m square base and 20.6 m perpendicular height. 4) What is the thickness of glass? 21 mm 5) What are the dimensions of the trapezium doorway? From Picture: 6 triangles across and 2 rhobi along diagonal height.

Finding the area of an Equilateral Triangle. 5 m 10 mm

Area of a Rhombus How do we find the area of a Rhonbus? 1 Split into 2 equilateral triangles 2 Area of rhombus = base x perpendicular height 5 m
