Rate of change of speed. It can be the units for acceleration but need not be.

A metre is a unit of distance. A square metre is a unit of area. The two units are therefore incompatible.
Acceleration is a change in velocity per unit of time. Velocity is distance (d) per unit of time (t). That makes acceleration distance per unit of time squared, or something like this:We have distance/time2, or d/t2Distance is commonly measured in meters, and time in seconds. This makes acceleration appear in meters per second per second, or meters per second squared, or m/sec2.m/s2meters per second squared
Because if speed is measured in meters per second (m/s) and time is measured in seconds, the SI unit of acceleration is meters per second per second (m/s2). ^_^
Acceleration is not measured in meters/second. Meters/second is a unit of speed. Since acceleration is defined as change of speed divided by time, the units are meters/second/second, usually written as meters/second2.
Surface area is the sum of the areas of all the surfaces of an object. When you add units, they stay the same. Since you are adding, let's say, meters squared and meters squared and meters squared, your unit is still meters squared. Volume is a measure of how much space is inside an object. To find volume, you must multiply length, width, and height. In our example, that would be meters x meters x meters. When you multiply units, they multiply to each other. So, we get meters cubed, or meters^3.
