The possible value of x = 4, dimensions 8 by 9 by 1 (option D), if the volume of a box is .
Step-by-step explanation:
The given is,
................................(1)
Step:1
Check for option A,
x = 1, dimensions 8 by 9 by 1
From the equation (1),
Volume =
= -24...................(2)
From the dimensions,
Volume = ( 8 × 9 × 1 )
= 72............................................(3)
From equation (2) and (3)
-24 ≠ 72
So, X=1; dimensions 8 by 9 by 1 is not possible.
Check for option B,
x = 1, dimensions 2 by 5 by 3
From the equation (1),
Volume =
= -24...................(4)
From the dimensions,
Volume = ( 2 × 5 × 3 )
= 30.........................................(5)
From equation (4) and (5)
-24 ≠ 30
So, X=1; dimensions 2 by 5 by 3 is not possible.
Check for option C,
x = 4, dimensions 2 by 5 by 3
From the equation (1),
Volume =
= 72.............................................(6)
From the dimensions,
Volume = ( 2 × 5 × 3 )
= 30............................................(7)
From equation (6) and (7)
72 ≠ 30
So, X=4; dimensions 2 by 5 by 3 is not possible.
Check for option C,
x = 4, dimensions 8 by 9 by 1
From the equation (1),
Volume =
= 72............................................(8)
From the dimensions,
Volume = ( 8 × 9 × 1 )
= 72............................................(9)
From equation (8) and (9)
72 = 72
So, X=4; dimensions 8 by 9 by 3 is possible.
Result:
The possible value of x = 4, dimensions 8 by 9 by 1 (option D), if the volume of a box is .

When solving an equation, we need to make sure that all variables are on one side and all numbers are on the other side.
Since we have numbers on both sides, we need to move all of them to one side:-
