Option D. 168 cubic units is the correct volume of triangular prism.
What is the volume of the prism?
The volume of a triangular prism can be calculated by taking the product of the area of the triangular base and the height of the prism which is also known as the length of the prism.
Volume=1/2(bhl)
Where b is base,
h is height,
and l is length of triangular prism
How to calculate the volume of the prism?
We have given, base b=7 units
height h=6 units and length l=8 units
Volume of triangular prism=1/2(bhl)
Substitute the value of b,h and l in the above volume formula of triangular prism,
Volume=1/2(7×6×8)
Volume=1/2(336)
Volume=168 cubic units
