Question 1045129: Jose has a fish tank that measures 11.8 inches wide,19.7 inches long, and 15.7 inches deep. He empties it halfway to clean it. To refill it when he is done, he will fill a one gallon jug in the sink and carry it to the tank, pour it in, and then return to the sink again. Convert the dimensions of the tank to centimeters. Round all measurements to the nearest whole number. Then tell how many liters does Jose need to add to the tank to fill it? ( reminder 1 liter= 1000 cubic centimeters). then tell how many times will Jose need to carry the jug from the sink to the tank?

I hope these are the right conversions:
1 US gallon = 3785.412 cm3
1 inch = 2.54 cm
-------------------------
+11.8%2A%28+2.54%2F1+%29+=+29.972+ cm
+19.7%2A%28+2.54%2F1+%29+=+50.038+ cm
+15.7%2A%28+2.54%2F1+%29+=+39.878+ cm
-------------------------
He empties it half way, so
+39.878%2F2+=+19.939+ cm
------------------------
The volume of the half-filled tank is:
+30%2A50%2A20+=+30000+ cm3
( dimensions rounded off )
-------------------------------
The cubic cm needed to fill the tank is:
+30%2A50%2A20+=+30000+ cm3 also
-------------------------------
Convert to liters:
+30000%2A%28+1%2F1000+%29+=+30+
Jose needs 30 liters to fill the tank
--------------------------------
How many gallons go into +30000+ cm3 ?
+30000+%2F+3785.412+=+7.925+
------------------------------
Jose needs to carry the jug 8 times from sink to tank
---------------
