A box has faces with areas 3, 12 and 25 square centimetres. What is
the volume of the box?
Use a single sheet of A4 paper and make a cylinder having the greatest possible volume. The cylinder must be closed off by a circle at each end.
What happens to the area and volume of 2D and 3D shapes when you
My measurements have got all jumbled up! Swap them around and see
if you can find a combination where every measurement is valid.
Can you choose your units so that a cube has the same numerical value for it volume, surface area and total edge length?
Have a go at this 3D extension to the Pebbles problem.
In the ancient city of Atlantis a solid rectangular object called a
Zin was built in honour of the goddess Tina. Your task is to
determine on which day of the week the obelisk was completed.
What is the greatest volume you can get for a rectangular (cuboid)

This jar used to hold perfumed oil. It contained enough oil to fill
granid silver bottles. Each bottle held enough to fill ozvik golden
goblets and each goblet held enough to fill vaswik crystal. . . .
Imagine two identical cylindrical pipes meeting at right angles and think about the shape of the space which belongs to both pipes. Early Chinese mathematicians call this shape the mouhefanggai.
These formulae are often quoted, but rarely proved. In this article, we derive the formulae for the volumes of a square-based pyramid and a cone, using relatively simple mathematical concepts.
According to Plutarch, the Greeks found all the rectangles with
integer sides, whose areas are equal to their perimeters. Can you
find them? What rectangular boxes, with integer sides, have. . . .

What shape funnel would use the least amount of plastic to
manufacture for any specific volume ?
If the radius of the tubing used to make this stand is r cm, what is the volume of tubing used?
An irregular tetrahedron has two opposite sides the same length a
and the line joining their midpoints is perpendicular to these two
edges and is of length b. What is the volume of the tetrahedron?
