Explanation:
volume of triangular prism= area of cross section *length
volume of triangular prism= area of cross section *lengthv=(1/2bh)l
volume of triangular prism= area of cross section *lengthv=(1/2bh)lv=?,b=5,h=40
volume of triangular prism= area of cross section *lengthv=(1/2bh)lv=?,b=5,h=40 =(1/2*5*7)40
volume of triangular prism= area of cross section *lengthv=(1/2bh)lv=?,b=5,h=40 =(1/2*5*7)40 =(35/2)40
=17.5*40
=700cm³
The volume of triangular prism is 700cm³
