Question

Volume of a cuboid is 5x^2 -125 .The possible dimensions are
1) 3,3,3
2) 5(x+5), (x-5)
3) x^2(5-x)
Please provide full solution

Answer 1

Answer:

5(x+5)(x-5)

Step-by-step explanation:

Volume of a cuboid is given by =l×b×h

Given,

3(x²-25) (taking common)

=3(x²-5²) using identity a²+b²=(a+b)(a-b)

=3(x-5)(x+5)

Therefore, the possible dimensions are 5,(x+5),(x-5)
