Answer:
C :)
Step-by-step explanation:
We take the numbers, add them together, then divide by the how many numbers there are:
(34 + 68) / 2
(102) / 2
51
The formula for volume is l x w x h.
To find the missing link, we do the equation backwards.
l x 2.5 x 5 = 75
If we divide 75 by 5 then by 2.5, we get 6 which becomes our length.
To check, do 5 x 2.5 x 6 which should equal 75
6 is your length
