The formula for finding the area of a regular hexagon when you know its side length is
, where
is the area and
is the side length.
- Substitute in the side length.

- Simplify the exponent.

- Multiply.

- Divide.

is as simple as the solution can get without estimating, but you can estimate with a calculator to find that it is approximately 2338.26859.
A tetrahedron is a triangular pyramid. It has four triangular faces and four vertices.
In the question, we are told that the length of the edges are all equal = 20m and the length from one corner to the center of the base = 11.5m
We sketch a diagram of a tetrahedron with the given measurement as shown below
To find the height, we will use the Pythagoras theorem
20² = h² + 11.5²
h² = 20² - 11.5²
h² = 267.75
h = √267.75
h = 16.36 (rounded to two decimal places)
