Answer:
The width of the rectangular prism is 9 cm.
Step-by-step explanation:
From the formula of the volume of a bar we see that cm.
If you notice, <span>8, 16, 32, 64 <--- 8 * 2 is 16, 16 * 2 is 32 and so on.
so, you get the next term's value by simply multiplying the "current term" by 2. So is a geometric sequence then.
therefore, the "common ratio" or multiplier is 2, and the first term's value is 8.
