Given information

The width of the triangular end is 8 m and it is equilateral with vertex at the bottom.

 

Step-by-step explanation

Step 1.

Since the triangle is equilateral with side 8 cm,obtain the height of the triangle by aplying pythagoras theorem into the triangle having sides 4cm, and hypotenuse 8cm.

 

While the depth increases by  , the width decreases by 8 m. So, at any depth h from the surface of water, the width w of the plate is given by 

              

           

So,Compute the area   of a thin horizontal strip of the triangle of thickness dh at this depth h.
