I NEED TO DO THIS


Material Weight (kg / dm3) Price (euro / dm3)
Marbel 2,7 20
Stone 2,6 15
Tree 0,6 7


these three item have diffrent price and diffrent weight.

Programming based on for users input: Height, width, length and material, than calculate the volume, weight and price and this must be write out on summary way.

programm must be writte like this exampel:

Add height:4


Add width:5


Add Length:5


(1)Marmor
(2)Sten
(3)Tra
Add number: 2 <<exampel 2 the 2 is stone

Material Volume(dm3) Weight(kg) Price(euro)
-------- --------- -------- --------
