using the relationship between distance/ speed / time
distance = speed × time
speed =

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 
5x+4+8x-3=79
13x=79-1
x=6
DBC=34
ABC=45
6x+20+2x+4 = 180
8x = 156
x=19.5
TQS=137
RQS=43
