Question 729402
 A plastic container is in the shape of a rectangular prism.
 Its base has an area of 30 square inches. Its height is 7 inches.
 The plastic container is filled to the top with water and emptied into a fish tank. 
The fish tank has a base that is 20 inches by 8 inches, and it has a height of 14 inches.
How high will the water reach up the side of the fish tank?
:
Find the volume of the water in the plastic container:
V = 30 * 7
V = 210 cu/inches
:
Find the height (h) of the water in the tank
20 * 8 * h = 210
160h = 210
h = 210/160
h = 1.3125 inches
