Answer
False.
Work Step by Step
Surface area may be defined as the total outer surface area of a solid figure which is three-dimensional in nature. The surface area of a three-dimensional object is measured in terms of square units.
For instance, the surface area of rectangle solid can be computed by adding the area of all the six outside rectangles of the object. The six rectangles would include Top and bottom, back and front left and right. In this way, the formula for surface area of rectangular solid would be as follows:
\[SA=2\left( lw+wh+lh \right)\]
Here, SA represents the surface area, l represents length, w represents width and h represents height.
Hence, the given statement is false.
