The volume of a triangular prism is:
[tex]V=Bh[/tex]
where B is the area of the base, in this case the area of the base is:
[tex]B=\frac{1}{2}\cdot2.8\cdot4.8=6.72[/tex]
Plugging the value of the volume and the area of the base we have:
[tex]\begin{gathered} 26.88=6.72h \\ h=\frac{26.88}{6.72} \\ h=4 \end{gathered}[/tex]
Therefore g is 4 mm. (since h and g are the same)
