Answer:
840 cm³
Step-by-step explanation:
To find it's volume , let's just divide the whole prism into two rectangular prisms.
Rectangular Prism 1:
Volume = [tex]Length * Width * Height[/tex]
Volume = 8 * 15 * 6
Volume = 720 cm³
Rectangular Prism 2:
Volume = [tex]Length * Width * Height[/tex]
Volume = 5 * 4 * 6
Volume = 120 cm³
Whole Prism:
Volume = 720+120
=> 840 cm³
