Strangely, men bet not to cover mass burial (10)

I believe the answer is:

entombment

'burial' is the definition.
('entombment' can be a synonym of 'burial')

'strangely men bet not to cover mass' is the wordplay.
'strangely' indicates anagramming the letters.
'to cover' is an insertion indicator.
'mass' becomes 'm' (symbol used in Physics e.g. f=ma).
'men'+'bet'+'not'='menbetnot'
'menbetnot' is an anagram of 'entobment'.
'entobment' placed around 'm' is 'ENTOMBMENT'.

(Another definition for entombment that I've seen is " Form of burial".)

I've seen this clue in The Telegraph.
