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.

mars1129 [50]

Answer:

150 mins or 2 hrs 30 mins

Step-by-step explanation:

This is simply the LCM ( lowest common multiple)

therefore, you find all the prime factors of 25 using a tree diagram resulting in 5^2 and 30 which will be 2 x 3 x 5. Then you multiply all the factors together and you will get 5 x 5 x 2 x 3 = 150

so....

the answer is after 150 mins

or 2 hours and 30 minutes
