Nature center has a fish tank shaped like a rectangular prism that measures 6 feet long by 4 feet wide by 4 feet high. It can be stopped safely with three small fish in each cubic foot of water. How many small fish can fit safely in the tank question?

192 fishes

Step-by-step explanation:

The tank is a rectangular prism, so its volume can be calculated multiplying its length, width and height:

Volume = 6 * 4 * 4 = 64 ft^3

For each cubic foot, it's safe to put 3 small fish, so the number of fishes that can be safely put into the tank is calculated with the following rule of three:

1 cubic foot -> 3 fishes

64 cubic feet -> X fishes

1/64 = 3/X

X = 64*3 = 192 fishes
