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?
How many liters does Jose need to add to the tank to fill it?
How many times will Jose need to carry the jug from the sink to the tank?

Thank you for the opportunity to help you with your question!

I inch = 2.54 cm

width = 2.54 * 11.8 = 29.972 cm

length = 2.54 * 19.7=50.038 cm

height = 2.54 * 15.7 = 39.878 cm


volume of tank to be filled = 1/2 * 29.972 * 50.038 * 39.878 = 29,903.2946 cm^3

to litres = 29,903.2946/ 1000 =  29.9033 liters


1 us gallon = 3.78541 liters

Times that Jose will need to carry the jug from the sink to the tank

= 29.9033/3.78541

= 7.8996

= 8 times
