ANSWERS

1. Sketch of the net of the solid (not freehand) base n\must be square, other lengths must be within. Labeling of all verticals with the path correctly shown. AB and DA may be shown one.
   
2. 1. 
      
   2. Total surface area
      = 2 √(9 x 3 x 4 x 2) + 10 (6 + 5 + 7)
      = 29.39 + 180= 209.4cm²
