Answer:
192cm^3
Step-by-step explanation:
V=Bh
B= 1/2bh
B= 16
h=12
V= Bh= 16 x 12= 192

If the 5 scores have a mean of 8, then their total sum would be 8*5 = 40
Now if one score if added (let's call this score x), there are 6 scores and the mean changes to 9, thus:
(40 + x)/6 = 9
40 + x = 54
x = 14
1/3 because reciprocal is the opposite
