To find the total surface area of the rectangular solid (or 3D shape), we need to first understand the provided dimensions. It appears that you provided the lengths of the edges of a rectangular prism.
Assuming the solid is a rectangular prism, the dimensions can be interpreted as follows:
- Length (l) = 6 cm
- Width (w) = 3 cm
- Height (h) = 2 cm
The formula for the surface area (SA) of a rectangular prism is: \[ SA = 2(lw + lh + wh) \]
Now, substituting in the values: \[ SA = 2((6 \times 3) + (6 \times 2) + (3 \times 2)) \] \[ SA = 2(18 + 12 + 6) \] \[ SA = 2(36) \] \[ SA = 72 , \text{cm}^2 \]
Thus, the total surface area is 72 cm².
