Which of the following option is correct?
S1 : Total surface area of a cuboid is the sum of areas of 4 faces excluding top and bottom faces.
S2 : Lateral surface area of a cuboid is the sum of areas of 4 faces excluding top and bottom faces.
S3 : Area of a face of a cuboid is of the form xy, where x and y are length and breadth respectively.
S2 and S3 are true
A cuboid has 6 faces.
Total surface area is defined as the sum of the areas of all 6 faces.
Lateral surface area is defined as the sum of areas of 4 faces which excludes the area of the top and bottom faces.
Area of a face of a cuboid = lb
Where l is the length of that face of the cuboid, b is the breadth of that face of the cuboid
