I am not sure where we differ but my answer is $3$ times yours. Need a deep-dive on the concept behind this application Look no further. The volume is then $23.38 \times 15 = 350.74$ cubic centimeters. In an answer to a previous question Stephen gave an expression for the area of a regular hexagon with $n$ sides and side length $a$ units. A hexagonal prism is a polyhedron with 8 faces, 18 edges, and 12 vertices where out of the 8 faces, 6 faces are in the shape of rectangles and 2 faces are in the shape of hexagons. If the base were a circle of radius 3 cm rather than a hexagon then the area of the base would be $\pi r^2 = \pi \times 3^2.$ but $\pi$ is approximately $3$ so the area of the base is $3 \times 3^2 = 27$ square centimeters.The height is $15$ cm so the volume is approximately $27 \times 15 = 405$ cubic centimeters.Īt this point I am not convinced by the book's answer or yours. The top and bottom of the hexagonal prism is shaped as a hexagon and are equal to each other. Multiply the perimeter of the end face by the.
#Find volume of a hexagonal prism how to#
First I did a "back of the envelope" calculation to approximate the volume. A hexagonal prism is a polyhedron with 8 faces, 18 edges, and 12 vertices where out of the 8 faces, 6 faces are in the shape of rectangles and 2 faces are in the shape of hexagons. How to calculate the surface area of a prism Work out the area of each rectangle separately, length × width.
I assume the book means a regular hexagon. How to Calculate the Volume of a Hexagonal Prism Solved Examples Practice Problems Frequently Asked Questions What is a Prism A prism is a three-dimensional solid figure with flat faces and two identical bases. To calculate, enter a side length of the base and the volume or height. The book that I am working from says that the answer is 77.94cm(cubed) but no matter what the equation I use I always get the answer 116.9/117. How to find the volume of a regular hexagonal prism Sixth grade and seventh grade math measurement. This function calculates the height or volume of a regular hexagonal prism. I am being asked to find the volume of a hexagonal prism, base edges are 3cm, and a height of 15cm. Sides The side faces of a prism are parallelograms (4-sided shapes with opposite sides parallel) These are all Prisms: and more Example: This hexagonal ice crystal.

Bases The ends of a prism are parallel and each one is called a base. So, in your situation, someone as already multiplied 2 of the dimensions for you since you were given the area of.
Once you multiply the the 3rd measurement, you get the volume. Give your answer in degrees to the nearest16 cminteger.7 cmBy first finding cos z, work out the size ofangle. To calculate the volume of a hexagonal prism you can use the formula for all prisms, where the area of the base is multiplied by the length of the prism. The video tells you the formula is: Volume Length (Width) (Height) If you multiply any 2 of these measurements, you get the area of one side (comparable to your base).
