What is definition of area?
area is the amount of space on a flat or 3d figure
What does it mean to find the area of a shape?
To find the the area of a shape is to find the space that is enclosed within a 2D object. Do not mix it up with volume, which is the space enclosed within a 3D object.
Introduction of surface area and volume?
Surface area is the amount of space on the face of a 2D side, like a piece of paper. And to find this we use (for 4 sided object); A = lh where l = length and h = height. This formula changes as the number of sides increase or decrease. Volume is the amount of space inside a 3D object, like a cube. To find this we use(for a 6 sided object); A = lbh where l = length, b = breadth and h = height.
Can 4D objects exist in your 3D world?
We don't actually know how many dimensions there really are. Certain theoretical considerations imply that there are at least 10 or 11, it's just that most of them are "curled up small" and we don't notice them. That said, a 4D object cannot fully exist in a 3D space. However, a 3 dimensional "slice" of them can exist in that space, just like a 2D "slice" of a 3D object can exist in a 2D space.
Is 3d area of anything possible?
Yes, the concept of three-dimensional area, also known as volume, is possible and is used to measure the amount of space occupied by an object in three dimensions. In mathematics, it is calculated by multiplying the length, width, and height of an object. In the real world, it has practical applications in fields such as architecture, engineering, and manufacturing.
