How to calculate the space you will need to have delivered. A cube is just an amount of space 1m high x 1m wide x 1m deep. The volume inside that space. It can be represented within a buffet 1.6m long x .45m high x .61m deep = 1.6 x.45 x.61 = .44 of a cubic metre. A Day bed 1.5m long x .6m wide x .6m deep = .54 plus .44 (buffet) equals .98. Then you add 10% for packing materials and space totalling 1.08cube x $600 cost per cube = $648. Hope this helps you do some estimates.
