The sum of length , breadht and hight of a cuboid is 19 cm and its diagonal is 5sqrt5 cm . Its surface area is

Assertion : The sum of the length, breadth and height of a cuboid is 19 cm and its diagonal is 5sqrt5 cm. Its surface area is 236 cm^(2). Reason : The lateral surface area of a cuboid is 2(l + b).

The sum of length, breadth and depth of a cuboid is 12 cm and its diagonal is 5sqrt(2) cm. Find its surface area.

If the sum of the length, breadth and depth of a cuboid is 20 cm and its diagonal is 4 sqrt5 cm, then its surface area is
