The area is defined as the region covered by two-dimensional shapes. The area of different shapes depends on their dimensions. The 2d shapes include circle, triangle, square, rectangle, parallelogram, pentagon, hexagon, etc. Hence, all these shapes have different areas. It is measured in square units.
Volume is a parameter that is defined only for three-dimensional objects. For each three-dimensional shape, such as sphere, cube, cuboid, cylinder, cone, etc., the volume is different. It is measured in cubic units.
The key difference between area and volume is: the area is the region covered by a 2d-shape whereas volume is the space occupied by a 3d shape.
