Find the volume of a regular hexagonal prism with each edge equal to 2.
July 8, 2021 | education
| In order to solve the problem, recall the formula for finding the volume of a prism:
Prism volume – base area multiplied by height:
V = S main * h.
The base area consists of 6 regular triangles:
Sb = 6 * S treug.
Let’s find the area of one regular triangle:
S triang = 1/2 * a * b * sin (α), where a and b are the sides of the triangle, sin (α) is the angle between them.
S triug = 1/2 * 2 * 2 * sin60 = 1/2 * 2 * 2 * √3 / 2 = √3 sq. units
Sb = 6 * √3 = 6√3.
V = 6√3 * 2.
V = 12√3 cubic meters units
Answer: V = 12√3 cubic meters. units
