K is a rectangular solid. Find the volume of K

(1) a diagonal line across the front face of K has a length of 40

(2) a diagonal line across the bottom face of K has a length of 25

Kudos for a correct solution.

Rectangular solid refers to a Cuboid.

FROM STATEMENT - I ( INSUFFICIENT )We can not find the volume of the Cuboid from the dimension of one diagonal.

FROM STATEMENT - II ( INSUFFICIENT )Same as statement I , We can not find the volume of the Cuboid from the dimension of one diagonal.

\(

FROM STATEMENT I AND II ( INSUFFICIENT )\)

We can not find the volume of a cuboid from the dimension of 2 diagonals , because the Volume of a Cuboid given the 3 diagonals as a , b and c is -

\(Volume \ of \ Cuboid = \sqrt{a^2 + b^2 + c^2}\)

Thus Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed , answer will be (E)
