A technical machinist is asked to build a cubical steel tank that will hold 195 L of water. Calculate in meters the smallest possible inside length of the tank. Round your answer to the nearest 0.001 m.

The smallest possible inside length of the tank is m.

Explanation:

As we know that

Thus, volume of liter tank is also equal to cubic meter

The volume of a cube is equal to , where, x is the length of the side of the cube

With the give condition,

Solving the above equation, we get -

The smallest possible inside length of the tank is m.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
