Question

If the volume of a cuboid is 3x² − 27, then its possible dimensions are

(a) 3, x², − 27x

(b) 3, x − 3, x + 3

(c) 3, x², 27x

(d) 3, 3, 3

Answer 1

We have to find the possible dimension of cuboid

Given: volume of cuboid

Take 3 as common factor

Using identity

We get,

Here the dimension of cuboid is 3,

The correct alternate is .
