the volume of a rectangular prism is = 297 cube inch
the volume of a triangular prism is = 216 cube inch
the volume of a cylinder = 8491 cube mm
the volume of a cylinder = 1146 cube mm
Step-by-step explanation:
attachment 1
the volume of a rectangular prism is = length X breadth X height
= 11 X 9 X 3 cube inch
=297 cube inch
attachment 2
the volume of a triangular prism is = [tex]\frac{1}{2}[/tex] X a X c X h
= [tex]\frac{1}{2}[/tex] X 2 X 12 X 18 cube inch ( here a = 2 , c = 12, h = 18)
= 216 cube inch
attachment 3
the volume of a cylinder = pi X radius^2 X height
= 3.14 X [tex]13^{2}[/tex] X 16 cube mm ( here pi = 3.14)
= 8490.56 cube mm
=8491 cube mm
attachment 4
diameter = 16 mm
radius = 16/2 mm = 8 mm
so the volume of cylinder = pi X radius^2 X height
= 3.14 X [tex]8^{2}[/tex] X 5.7 cube mm ( here pi = 3.14)
= 1145.47 cube mm
= 1146 cube mm
