Q6 of 76 Page 18

The sum of the length, breadth and depth of a cuboid is 19 cm and its diagonal is 5 cm. Its surface area is

Given,


Sum of length ,breadth, height of cuboid = 19 cm


Diagonal of cuboid = 5√5 cm


=


(Squaring both side )


=


∵


Putting values …


= 192 = 125 + 2


=


= surface area of cuboid = 236 cm2
