The area of a 2D form is the amount of space within its perimeter. The surface area of the given composite figure is 456 cm².
What is an area?
The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The surface area of the composite figure is the area that is on the surface of the area. It does not include the area in which the two block touch each other. Therefore, The surface area of the composite figure can be written as,
Surface area = (14×8) + 2(2×14) + 2(2×8) + 2(6×8) + 2(6×4) + (4×8) + (10×8)
= 456 cm²
Hence, the surface area of the given composite figure is 456 cm².
