Find the total area of the regular pyramid.
5 months ago
Q:
Find the total area of the regular pyramid.
Accepted Solution
A:
check the picture below.
notice, the base of the "square" pyramid, is a square, and it has 4 triangular faces with a base of 2, and a height of √(10).
so the total surface area is the area of the base plus all 4 triangular faces' areas.
[tex]\bf \stackrel{\textit{squarish base}}{(2\cdot 2)}~~~~+~~~~\stackrel{\textit{4 triangular faces}}{4\left[ \cfrac{1}{2}(2)(\sqrt{10}) \right]}[/tex]
