Find a formula for the exponential function passing through the points (-3, 5/27) and (3,135). Write in the form y=ab (power of x). Couldn't figure out how to write the x

The answer is 16.66 i'm pretty sure

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !
