Answer:
x = 2.25 (Approximately)
Step-by-step explanation:
4 + 3x^4 = 81
4 - 4 + 3x^4 = 81 - 4
3x^4 = 77
(3x^4)/3 = 77/3
x^4 = 25.67 (Approximately)
x = 2.25 (Approximately)
The equation rx3+1 can be used to solve the problem,and your answer ends up being 7.

Step-by-step explanation:
You need to use the following formula to find the volume of a Square pyramid:

Where "s" is the edge of a side of the square base and "h" is the height of the pyramid.
Knowing that:

You can find the volume of the Pyramid A and the volume of the Pyramid B:

Finally divide the volume of the Pyramid B and the volume of the Pyramid A, in order to find how many times bigger than the Pyramid A is the Pyramid B.
You get:

AB being the longest and is opposite the right angle.
Answer (B)
