Question

Possible dimensions of Cuboid whose volume 3x2 - 12x is:
(A) 3, x, x + 4
(B) 3, X - 4, X
(C) -3, -x, -x - 4
(D) None of these
ANSWER IS B​

Answer 1

Answer:

Step-by-step explanation:

Volume of cuboid is

V=3x²-12x

=3x(x-4)

This can be written as:

V=3× x ×(x-4)

Volume V=a × b × c

On comparision

a=3 b=x and c=x-4

So dimensions are:

3,x,x-4 Or 3,x-4,x

option(b) is correct
