Wewaii [24]

Answer:

The surface area of the model pyramid is 451\ in^{2}

Step-by-step explanation:

we know that

The surface area of the pyramid is equal to

SA=B+LA

where

B is the area of the base of the pyramid

LA is the lateral surface of the pyramid

<em>Find the area of the base B</em>

B=11^{2}=121\ in^{2} -----> is a square

<em>Find the lateral surface area of the pyramid LA</em>

we know that

The lateral surface area is equal to the area of its four triangular faces

LA=4[\frac{1}{2}(11)(15)]=330\ in^{2}

<em>Find the surface area of the pyramid</em>

Substitute the values

SA=121+330=451\ in^{2}
