Area is a two-dimensional measurement of a shape or object — think length and width — while volume is a three-dimensional measurement — think length, width, and height (or depth, or thickness.)
Two-dimensional objects — a shape printed on a flat piece of paper, for example — have length and width, but no thickness, so they have area but zero volume.
Three-dimensional objects — physical things that take up space, that would splash water out if you dumped them in a full pool (like a car, person, or rock), or that you could fill with smaller objects, like a bucket or empty pool — have length, width, and height, so they have non-zero volume. Three-dimensional objects also have surface area; think about how much wrapping paper it would take to perfectly cover every surface.
Area is measured in square units or units squared, such as square inches or cm2cm2; if you multiply length times width, you also multiply the units. (An 8-inch by 10-inch photograph has an area of (8 in.)×× (10in.) = 80 in2in2. (For solid objects, think about completely covering it in paper squares, though you’d probably have to cut some of them into smaller pieces to cover all the area.)
Volume is measured in cubic units or units cubed, such as cubic centimeters or in3in3. If you multiply length times width times height, or ππtimes radius squared times height (for a cylinder), the three units also multiply. For solid objects, think about filling all the space it takes up, or all of its empty space, with cubes (or cut-up pieces of cubes.
