Given :
Square-based pyramid that has base edges measuring 6 units and lateral edges measuring 5 units.
To Find :
The total area, in square units, of the four triangular faces of a right.
Solution :
We know, area of square based prism is given by :
[tex]A = a^2 + \dfrac{ah}{2}[/tex]
Here, a is the length of square base and h is the height .
[tex]A = 6^2 + \dfrac{6\times 5}{2}\\\\A = 51 \ units^2[/tex]
Therefore, total area in square units is 51.
