Answer:

The surface area of the model is [tex]SA=240\ m^{2}[/tex]

Step-by-step explanation:

we know that

The surface area of the square pyramid is equal to the area of the square base plus the area of four lateral triangles

so

[tex]SA=10*10+4(\frac{1}{2}(10)(7))\\ SA=100+140\\SA=240\ m^{2}[/tex]
