Answer:
The total surface area is 896 
Step-by-step explanation:
<em>The square pyramid is a solid with square base and symmetric 4 triangular faces.</em>
Given that the square base is 14 m and height is 24 m.
The apex of pyramid, center of square and center of any edge of square make a right angled triangle.
Let that height if triangular face be "x".
by pythagoras theorm , 
x = 25 m
the area of square base is 
the area of each triangular side is <em>
</em>
such are 4 triangles, thus 
Thus the total surface area is 196 + 700 = 896 
Answer:
-7+1x (ignore this I needed more characters)
I'm not sure what this answer is but I need some points I hope you find the answer
