## Help! What do i do???

Question: You decide you would like to concrete the alfresco area.

Due to budget restrictions you can only afford 1.5m cubed of concrete. Assuming, for aesthetic purposes, the concrete will need to line up with at least one of either the western external wall or the eastern external wall of the house. Council regulations require that the depth of concrete to be 100mm deep.

Determine all the possible ways the concrete slab could satisfy these requirments by calculating the dimensions for each. State and justify which slab is the most practical and why. Include a labelled diagram that clearly shows the shape and dimensions (in mm) your final concrete slab

Please help, i havent a clue what to do :S

My initial thoughts are:

V= AH

1.5 = A X 100mm

A = 1500/100

A = 15

.... idk how that helps

or

1.5cubed = 6500 x W x 100mm

or

1.5cubed = L x 3300 x 100mm

ANY IDEAS WOULD BE GREATLY APPRECIATED
