7) The height of a box is represented by the expression (x.- 2) centimeters. The volume of the same box is
represented by the expression (x3 - 8 ) cubic centimeters.
Which expression below represents the area of the base of the
box?
A. x2 – 2x + 4
B. x2 + 2x + 4
C. X? + 6x - 4
D. x2 - 6x + 4

Given:

Height of box = (x-2)

Volume of box =

To find:

The expression for the base area.

Solution:

We know that,

Volume of a box(V) = Base area(B) × Height(h)

On substituting the given values, we get

So, the base area is .

Therefore, the correct option is B.

1. 3. can also be expressed as (22/7)

2. -4.5
