Solid shape of Cheddar one chopped up (10)
I believe the answer is:
decahedron
'solid shape' is the definition.
'decahedron' can be an answer for 'shape' (decahedron is a kind of shape). I'm unsure of the 'solid' bit.
'cheddar one chopped up' is the wordplay.
'chopped up' is an anagram indicator.
'cheddar'+'one'='cheddarone'
'cheddarone' with letters rearranged gives 'DECAHEDRON'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for decahedron that I've seen before include "Ten-faced solid" , "Solid figure with ten plane faces" , "Ten-faced figure" .)
