please help me find volume on this one. Height, h=8 cm

Given:
The base of the triangle, b = 6 cm.
Height of the triangle, h = 8 cm.
The length of the figure is l = 14 cm.
To find the volume of the figure:
The volume formula is,
[tex]\begin{gathered} V=\text{Area of the triangle }\times\text{ length} \\ =\frac{1}{2}\times b\times h\times l \\ =\frac{1}{2}\times6\times8\times14 \\ =336cm^3 \end{gathered}[/tex]Thus, the volume of the figure is 336 cubic cm.
