Answer 1

Hi!

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

Area of a triangle = $(base * height)/2$

Area of a square = $(side)^2$

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

QUESTION 1: Determine the area of the triangular face.

$\frac{bh}{2}$

$32(20)/2$

$640/2$

$320$

The triangular face is 320 square feet.

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

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

$a^2$

$32^2$

$1024$

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

$1024+320(4)$

$1024+1280$

$2304$

The total surface area is 1204 square feet.
