Answer:
A) 39
Step-by-step explanation:
If you calculate the volume of the cube which is the V=a^3 you get 27, then calculating the pyramid, the Length is 3, and the Width is also 3. Then the height is 4. so you put that into the formula to calculate the volume which is V=L*W*H
--------
3
you get 12. Now its simple, you just add the 2 volumes, so you do 27+12 and its 39.
So 12.44 hours=460.28 oz
divide
so
oz/hour means hour=1 so divide
460.28/12.44=37/1
the answer is 36 fluid ounces per hour
