When the height (h) = 19 units and the base edge (s) = 10 units of the given squarebased pyramid, calculate the information below to the nearest tenth:

What is the slant height?  l = u  
What is the area of one lateral face?  A_{tri} = u^{2} 
What is the lateral area?  LSA = u^{2} 
What is the area of the base?  B = u^{2} 
What is the total area?  TSA = u^{2}
