Building compost bins - Week 10 Problem

 At Wesley we are eco friendly. We have been building compost bins to reduce rubbish and look after our environment. 

To build compost bins we used 5 planks of wood for each side of the compost bin. How many  planks of wood do we need to build 5 compost bins ? We also need a plank for the lid. 

If we plan to build 10 bins how many planks do we need altogether?  Draw picture, plan your build and share your solutions with us.
