Answer:
Length = 2.823 in (to 3 decimal places)
Step-by-step explanation:
assuming that the box is a cubic box:
volume of box = in³ = 22.5 in³
volume = Length × Length × Length = (Length)³
∴ (Length)³ = 22.5
∴ Length = ∛(22.5)
using the calculator punch ∛(22.5), and the answer is:
∴ Length = 2.823 in (to 3 decimal places)
The geometric mean of two numbers is the square root of their product.
sqrt{4 • 12}
sqrt{48}
sqrt{16} •sqrt{3}
4•sqrt{3}.
The geometric mean of 4 and 12 is
4•sqrt{3}.
