(a(i))[1]
Draw Diagram 4 on the grid.
(a(ii))[1]
Fill in the table.
(a(iii))[2]
Find an expression, in terms of $n$, that gives the perimeter of Diagram $n$.
(a(iv))[2]
One diagram in the sequence has a perimeter of 300 units. Work out its Diagram number.
(a(v))[3]
Calculate the volume of the box. Include the units in your answer.
(b(i))[1]
Write down how many lines of symmetry Diagram 3 has.
(b(ii))[2]
Finish the table.
(b(iii))[1]
Find a formula, in terms of $n$, that gives the total number of small triangles, $t$, in Diagram $n$.
(b(iv))[2]
Show that this formula produces the right number of white triangles when $n = 3$.
(b(v))[3]
Finish this statement for Diagram 15. When $n = 15$, $w = \ldots\ldots\ldots\ldots$, $g = \ldots\ldots\ldots\ldots$ and $t = \ldots\ldots\ldots\ldots$.
