Answer:
[tex]346.5 cm^3[/tex]
Step-by-step explanation:
Length of triangular prism,l=11 cm
Width of triangular prism,b=7 cm
Height of triangular prism=9 cm
We have to find the volume of triangular prism
Volume of triangular prism=[tex]Al[/tex]
Where A=[tex]\frac{1}{2}\times base\times height[/tex]=Area of base
l=Length of triangular prism
Area of base=[tex]\frac{1}{2}\times 7\times 9[/tex]
Area of base[tex]=\frac{63}{2} cm^2[/tex]
Substitute the values then we get
Volume of given triangular prism=[tex]\frac{63}{2}\times 11[/tex]
Volume of given triangular prism=[tex]346.5 cm^3[/tex]
