Acertain hexagonal prism has a volume of 160 cubic meters. its base has a perimeter of 30 meters and an area of 64 square meters. what is the surface area, in square meters, of the hexagonal prism?

Given:
hexagonal prism:
volume = 160 cubic meters
base perimeter = 30 meters
base area = 64 sq. meters

hexagon has 6 sides. 
30 meters / 6 = 5 meters

Base area of hexagonal prism = (3√3)/2  * a²
Volume of hexagonal prism = (3√3)/2 * a² * h

height of the prism = volume / base area = 160 cubic meters / 64 sq. meters = 2.5 meters

Base area = 64 sq. meters * 2 faces = 128 sq. meters. 
sides = 5 meters * 2.5 meters = 12.5 meters * 6 sides = 75 sq. meters

Surface area = 128 sq. meters + 75. sq. meters = 203 sq. meters

That’d be 9 years or something

The volume is 56.8 triangular the
