Answer:
The pattern is that each time, 8 is added. The next 2 numbers are 47, 55.
Step-by-step explanation:
7+8=15
15+8=23

39+8=47
47+8=55
Let
a--------> original side length side of a cube
we know that
[volume of a original cube]=a³
<span>If the side lengths are decreased to 50% of their original size
then
[volume of a new cube]=(a/2)</span>³----> a³/8
the answer is
the volume of the new cube is a³/8
<span>
B.
Both pairs of opposite sides are parallel</span>
14.5 x 5.5x 0.5 = 39.875 cubic feet for the wall
brick = .5 x .333 x 0.167 = 0.0278 cubic feet rounded to 0.03
39.875/0.03 = 1329.16
so approximately 1330 bricks are required.
This could be a little different depending on how you round everything off
