Question

the sum of length, breadth, and height of a cuboid is 14 cm and the length of the diagonal is
$5 \sqrt{5}$
find the total surface area of the cuboid


​

Answer 1

Answer:

as (A+B+C)² = A² + B² + C² + 2( AB + BC + AC )

Step-by-step explanation:

SO,

AS GIVEN WE CAN CONSIDER

LENGHT = A

BREADTH = B

HEIGHT = C

AS DIAGONAL IS. SQ. ROOT OF L² + B² + H²

THEN,

L² + B² + H² = 125

AND ALSO

L + B + H = 14

HENCE,

I THINK SO THAT FROM NOW YOU CAN SOLVE IT BY YOUR OWN !
