Answer:
72cm³
Step-by-step explanation:
Base of the triangular face =3 cm.
Height of the triangular face = 4 cm.
Length of the prism = 12 cm.
Volume of a Prism= Base Area X. length
The base of a triangle prism is a triangle, therefore:
Volume of a Triangular Prism= ½bh X Length
=½ X 3 X 4 X 12
=½ X 144
=72cm³
Volume of the triangular Prism= 72cm³
