If the length, breadth and height of a cuboid are equal, then its surface area is
6l2
6b2
6h2
All of these
Surface area of the cuboid = 2(lb + bh + lh)
= b = h = x
Surface area of the cuboid = 2(3x2) = 6x2 = 6l2 = 6b2 = 6h2
Surface area of a cylinder is the sum of the areas of
Lateral surface
Circular top
Circular base
Surface area of a cylinder is the sum of the areas of the lateral surface, circular top and circular base.
Total surface area of a cone is
Curved surface area
Area of the base
Curved surface area + Area of the base
Subtraction of A and B
Total surface area of a cone is the sum of the curved surface area and the area of the base.
Total surface area of a hemisphere is
Curved surface area of the hemisphere
Area of the base + Curved surface area of the hemisphere
None of these
Total surface area of a hemisphere is the sum of the area of the base and the curved surface area of the hemisphere.
