Answer:
8712

Explanation:
since the box was measured to the nearest 2 cm
we will assume its dimensions would be ( + or - ) 2cm each
hence for the smallest possible volume of the box the dimensions would be
= (24 - 2 ) cm * ( 24 - 2 ) cm * ( 20 - 2 ) cm
= 22 * 22 * 18 = 8712

this would be the smallest possible volume of the box to the nearest cm3
