Answer: 
Step-by-step explanation:
Given: The estimated distance from Earth to the moon
If the distance from Earth to the sun is approximately 400 times farther.
Then, the distance from Earth to the sun

Therefore, the approximate distance from Earth to the sun=
The problem involves the volume of the water of the rectangular tank, so first we must find the volume of our water. For the volume we have;

Therefore our tank has an initial volume of 6250 cm³, but if you drop a cube with a side measuring 10 cm. the volume of the water in our tank increases. Giving us the expression;

Since we already have the volume of the water (which is 6250), we just need to find the volume of the cube using the same formula (<em>Volume = Lenght x Width x Height</em>);

Therefore our new volume when they are combined or when the cube is droped in the tank is 7250 cm³.
But we must remember since our tank would remain it's shape no matter how much water it holds it would always retain it's dimension of it's lenght and width (25x25), therefore it is possible to find the height of the new water level using this logic;

Therefore the height of the new water level is 11.6 cm.
-6,-7, and -8, this is more of a guess and check question
