Answer:
g(3) is -12
Step-by-step explanation:
Given that
g(1)= -2
g(2)= 6
g(n)=g(n−2)⋅g(n−1)
Now the g(3) is
g(3) = g(3 - 2) . g(3 - 1)
= g(1).g(2)
= (-2) (6)
= -12
Hence, g(3) is -12
Answer: 343 cm³
Step-by-step explanation:
The surface area of a cube is 6s^2, where s is the side length of a square. Thus, first do 294/6 to get 49. Then take the square root of 49 to get that each side of the cube is 7. The volume of a cube is s^2, so simply do 7*7*7 to get that the volume of the cube is 343cm^3
