The doorstop is a triangular prism. volume of the triangular prism is the area of the base times the height
area of the base: 1/2 * 10*6=30cm²
height: 2.5cm
Volume: 30cm²*2.5cm=75cm³
weight: 75cm³*8.6g/cm³=645 grams
455, because if you do 5/12=0.416666..., and then you multiply that to 780 you would get 325, and then you do 780-325 to equal 455.
