Martin builds a right square pyramid using straws. a diagram of the pyramid and its net are shown.

what is the surface area of the pyramid?

enter the answer in the box.

in²

Step-by-step explanation:

We have been given diagrams of a pyramid and its net are shown.  We are asked to find the surface area of our given pyramid.

The surface area of our pyramid would be equal to the area of all faces of the given net of pyramid.

We can see that our given net consists 4 triangles ans one base square.

, where,

b = Base of triangle,

h = Height of triangle.

, where,  

a = Each side of square.

Therefore, the total surface area of the given pyramid would be 39 square inches.

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
