The surface area is 144 unit².
What is Surface Area?
The total area occupied by the surfaces of an object is called its surface area. In geometry, different 3D shapes have different surface areas which can be easily calculated using the formulas that we will be learning in this article. The surface area is classified into two categories:
- Lateral surface area or Curved surface area
- Total surface area
Types of Surface Areas
As we have already discussed that there are two types of surface areas for three-dimensional shapes: total surface area and curved/lateral surface area. The total surface area includes the area of all the faces of the shape while the curved or lateral area includes only the area of the side faces of the shapes.
Given:
w = 6 units, x = 3 units, and y = 5 units
Surface Area of figure is
=36+36+36+18+18
=144 unit²
