A frame is made from six straight pieces of wood.
Work out the total length of the wood in the frame.

48m

Step-by-step explanation:

Four pieces are easily found,

6m, 6m, 8m, 8m

The diagonal pieces can be found using Pythagoras theorem

+ =

Where c is the length of the diagonal piece and a and b are the two sides of the triangle

+ =

64 + 36 =

100 =

= c

c = 10

Remember there are two identical diagonal pieces

Total length of the wood = 6 + 6 + 8 + 8 + 10 + 10

Total length of the wood = 48m
