This task requires is about making boxes from grid paper and calculating the volumes.
|
For this task you are going to construct 3 different sized boxes (without lids) and calculate their volumes.
|
||
| a) |
Make three boxes, of different sizes, each from a piece of 12 cm× 12 cm square grid paper you have been given.
Label the boxes A, B, and C. Each box can only be made by cutting out a square or squares from each corner of your grid paper (an example is shown in the diagram below), and then folding up and cellotaping each side.
i.e.,  |
|
| b) |
Calculate the volume of each open box you have made.
Volume of Box A = ______________ Volume of Box B = ______________ Volume of Box C = ______________ |
|
| c) |
If you were now asked to make a box without a lid from a piece of 8 cm × 8 cm square grid paper (by cutting out squares from each corner), what dimensions would you construct to give it:
|
|
|
i) ii) |
maximum volume? _______________ minimum volume? _______________ |
