A right rectangular prism looks like a rectangular shoe box. It has 6 faces, all of which are rectangles. The formula for its volume is
V = whl, where w=width, h=height and l=length
From the statement of the problem:
h = 3w
l = 2w
Since all are in terms of w already, the volume could be expressed as a function of the width.
V = w × 3w × 2w
V = whl, where w=width, h=height and l=length
From the statement of the problem:
h = 3w
l = 2w
Since all are in terms of w already, the volume could be expressed as a function of the width.
V = w × 3w × 2w

Answer:
A
Step-by-step explanation:
The sequence of positive odd numbers is
1, 3, 5, 7, ......
This is an arithmetic sequence with common difference d
d = 3 - 1 = 5 - 3 = 7 - 5 = 2
The sum to n terms of an arithmetic sequence is
=
[2a + (n - 1)d ]
where a is the first term
here a = 1, d = 2, n = 12, hence
=
[1 + (11 × 2) ]
= 6 [ 2 + (11 × 2) ]
= 6 × 24 = 144 → A
