When Finding the volume of a triangular prism, First we must find the area of the base. What is the area of the base of the triangular prism? use the formula sheet provided.
Area = 1/2 bh
numbers on triangle:
3 cm
2 cm
7 cm
Area = cm ^2
(I got 21)
Area = 1/2 bh
Area = 1/2 * 3 cm * 7 cm
Area = 1/2 * 21 cm^2
Area = 10.5 cm^2
Therefore, the area of the base of the triangular prism is 10.5 cm^2.
