Common solids Questions
1. Below is a net of a model of a 3 – dimensional figure. The lengths AB = BC = AC = 6.0cm and lengths AF = FB = BD = CD = CE = AE = 8.0cm.
a) Sketch when the net is folded by taking ABC as the base and the height 5cm.
b) State the name of the figure sketched (3 mks)

2. Sketch of the net of the solid (not free hand) 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.
3. (a)
(b) Total surface area
= 2 9 x 3 x 4 x 2 + 10 (6 + 5 + 7)
= 29.39 + 180= 209.4cm2
