The dimensions of a box are measured to be 18.4 inches by 17.92 inches by 26 inches. the volume of the box can be found by multiplying these three dimensions. what is the volume of the box expressed to the correct number of significant figures?

-

The volume of the box is 8.6 x 10³ inch³ correct to 2 significant figures.

Explanation:-

The dimensions of a box are measured to be 18.4 inches by 17.92 inches by 26 inches.

We need to find the volume of the box.

We are told that the volume of the box can be found by multiplying these three dimensions.

Thus volume of the box = 18.4 inches x 17.92 inches x 26 inches.

                                         = 8572.928 inch³

                                          = 8.6 x 10³ inch³ correct to 2 significant figures.

The answer will be correct to 2 significant figures because 26 has just 2 significant figures.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
