What is th volume of an object?

• The amount of space occupied by the object or shape, which is in three-dimensional space

• The total distance around the shape

• The space covered by the figure or any two-dimensional geometric shape

• The total area occupied by the surfaces of an object

Answer explanation

The total area occupied by the surfaces of an object is called its surface area.

The space covered by the figure or any two-dimensional geometric shape, in a plane, is the area of the shape.

The perimeter of a shape is defined as the total distance around the shape.
