Step-by-step explanation:
The information that we kow about the shape of the aquarium:
length:

width:

when the reef is submerged, the water level rises 3 feet. The volume that those 3 ft represent in the aquarium will be the volume of the reef.
Thus, we calculate the volume of water "addition" with the same length and width as the aquarium but with a deep of 3 feet (thi is because the reef caused the water to rise 3 feet), and this is the volume of the reef that was added to the aquarium:

The volume of the stone is 
First, let's simplify this a bit ok?

Now, as a decimal: 3.5
As percent you multiply the number by 100 % (which is 1, and you an always multiply by 1):
3.5 *100%=350 %.
Answer:
He played 7/10 of the game
