What is the area of the bulletin board?

PLEASE HELP!!

B: 8^3 in squared

Step-by-step explanation:

2^3 = 2*2*2= 8

4^3 =4*4*4=64

Area of rectangle equals length times width.

So, 8 * 64 equals 512 and 8^3= 512

Use calculator. Also, you can just treat it as normal multiplication and choose the one with the same units. so it would be 8, but then the next thing you would need to look at is the exponent. Since 8^6 is not the same exponent as the two in the problem, it has to be the 8^3, which are the same
