Question

The sum of length, breadth and depth of a cuboid is 15 cm and the length of its diagonal is 12 cm.
The surface area of the cuboid is equal to:
(A) 71 cm
(B) 81 cm
(C) 96 cm
(D) 64 cm​

Answer 1

Answer:You can solve this problem only when you know some formulas related to cuboid

Step-by-step explanation

Length of diagonal of cuboid:D=√(l²+b²+c²)

Surface area of cuboid : SA=2(lb+bh+lh)

Now coming back to the question,

Assume :

length=l

Breadth= b

Depth=h
