Given a cube with a volume of 27 cm3, what is the volume of a square pyramid that can fit perfectly inside the cube?

 3cm

 6cm

 9cm

 12cm

mrnood · Answer

NOTE- the answers must be cm^3
VOLUME is always measured in 'cubes'

You start with a cube 27cm3 - it is easy to find the side of this

So - the pyramid has a base = to one side of the cube, and a height = to height of cube

the formula fro the volume of a square based pyramid is easy to find (your text, your head, gooogle ...)

so you have all you need
