Answer:
Option A
Volume of prism is, 180 cubic unit
Step-by-step explanation:
From the given figure , we have
The length of triangular prism is 6 unit .
Since in the triangular cross-section we have the base (b) equals to 5 unit and the height (h) equals to 12 unit.
Using Volume of triangular prism formula: - A triangular prism whose length is l units, and whose triangular cross section has base b units and height h units, then,
Volume(V) of the triangular prism in cubic unit is given by;
Putting the values of unit , b=5 unit and h = 12 unit.
⇒
on solving we get;
therefore, the volume of prism is, 180 cubic unit.
