If a cube is split in half, the surface area of the pieces will be that of the cube. a. greater than b. less than c. the same as d. none of these

If we are talking about BOTH the pieces surface areas the answer would be A. Greater than. This is because a split cube has an extra side on each piece that the original cube didn't have.

I hope that helps!!

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.
