Amount of region occupied by a solid is called its surface area. Is the given statement true
Solution :
The statement is False.
The amount of region occupied or enclosed by a solid is referred to as its Volume and not surface area.
✦Try This: State whether the given statements are True(T) or false(F).
(a) The area occupied by the cube of side ‘s’ is 6s²
(b) The lateral surface area of the a cube with side ‘s’ is 4s²
(c) The total surface area of a cylinder is 2πrh
(a) The statement is False because the statement has no meaning. One refers to a volume of a solid object like a cube and not the area! The correct statement would be the “ total surface area of the cube of side ‘s’ is 6s²”
(b) The statement is True.
A cube has a total of six surfaces. One on top and other at the bottom. The surfaces on the sides are referred to as the lateral surfaces and these are 4 in number and the area of these surfaces is 4s²
(c) The statement is False.
It is the lateral surface area of a cylinder which is equal to 2πrh and not total surface area. The total surface area of the cylinder with radius r and height h is 2π(r + h).
