You calculate the area of each face and sum them. Sometimes, some of the faces may be congruent and tat will save on the slog.
Area is usually pertaining to the area of a 2d object but surface is 3d object
The surface area is the area of every face of a 3D object, such as a cube or sphere. Area usually refers to a flat object, such as a circle or rectangle.
surface area is the area of a 3D object radius is half of the diameter of a circle
A 2D shape is flat and only has a surface area whereas a 3D shape is an object that has surface area and volume.
surface area is basically the total area of each surface of the 3d object. Sa = 2-D A = 3-D
A "perimeter" is a 2D measurement and cannot be applied to a 3D object. However, sometimes the area around a building or piece of property to be protected is known as a perimeter. In that case, measure the sides of the facet of the object facing the ground, add them up and you have a perimeter. "Surface area" would be the closest thing to a perimeter, purely speaking. Measure the area of one facet of an regular 3D object (such as a cube), multiply that number by the number of facets, and you get the surface area.
if a 2d object, height x width. if a 3d object, height x width x 6.
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.
Surface area is the area of all the sides of a 3D object, but area could be anything. e.g. Area is the surface of a 2D object or if you say the area of all the sides, it means the same as Surface area. -----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----= By Austin from Covenant Christian School
area is 2D and volume is 3D. think of volume as the amount of space inside a 3D object like a ball.
Well, a 2D object has only length and width, but a 3D object has length, width, and depth.
a 3d object is a object that isn't flat. for instance, a square in 3d form would be a cube
