It’s true!! Hope this helped!!!!
The pyramid consists of 4 congruent triangular faces, and 1 square base.
Area of 1 triangular face:
1/2 * (5 in)/2 * (5.6 in) = 7 in^2
Area of base:
(5 in)^2 = 25 in^2
Then the total surface area is
4 * (7 in^2) + 25 in^2 = (28 + 25) in^2 = 53 in^2
Answer:
Easy

To solve this problem you must apply the proccedure shown below:
By definition, an equilateral triangle has equal sides and all its internal angles are . If you divide it into two right triangles, you can apply the Pythagorean Theorem to calculate the height of the triangular base of the pyramid, as following:
Therefore, as you can see, the answer is:
