Question

1.It is the sum of all areas of lateral faces and bases of a solid figure
A. Base area
8. Lateral area
C. Surface area
D. None of the above
​

Answer 1

Answer:

the correct answer is surface area

Answer 2

Answer:

Total Surface Area

Step-by-step explanation:

As we all know any 3-Dimensional object or solid figure may have lateral face (mostly curved surface in many objects such as Cylinder) and base area (flate surface in most of the case). Total surface area is sum of Base area and  Lateral area.

For example, in case of cylinder of radius r and of height h we have,

$L= 2\pi rh\\B =2\pi r^2\,\,(\,two\,\,bases\,)$

Then Total Surface Area is given by,

A = $2\pi r (r+h)$
