Hi!

Area of a triangle = [tex](base * height)/2[/tex]

Area of a square = [tex](side)^2[/tex]

---------------------------------------------------------------------------------------------

QUESTION 1: Determine the area of the triangular face.

[tex]\frac{bh}{2}[/tex]

[tex]32(20)/2[/tex]

[tex]640/2[/tex]

[tex]320[/tex]

The triangular face is 320 square feet.

---------------------------------------------------------------------------------------------

QUESTION 2: Determine the surface area of the entire figure.

[tex]a^2[/tex]

[tex]32^2[/tex]

[tex]1024[/tex]

Now, add the 4 triangular faces to the area of the square face.

[tex]1024+320(4)[/tex]

[tex]1024+1280[/tex]
