Question

What is the shape of your instrument box?

Answer 1

Hint-Instrument box is rectangular in shape but we have to find out it’s three dimensional shape.

Let us consider an actual instrument box for an example

So, if we compare in this figure there are a total of 6 faces and also the opposite faces are identical
If a figure has six faces and only their opposites faces are equal, then the figure is a cuboid
So, the instrument box is in the shape of a cuboid.

Note: In general, the instrument box will be in the shape of a cuboid , but if it is specified that it is in a particular shape, then we have to consider that specific shape.
