Consider the situation where squares of side x cm are cut from the 21 cm square piece of paper. Suppose that the sides are folded up to form a box of height x cm.work out the length and breadth of the box in terms of x.ch
-------
Draw a square and label the sides "21 cm".
---
Sketch a square inside each of the 4 corners.
Label the side of each of the 4 squares as "x cm"
-----------------
Imagine cutting out those 4 small squares.
----
Imagine folding up the 4 flaps to form a box (with no top).
---
The length of the baee of the box is (21-2x) cm
The width of the base of the bos is (21-2x) cm
