Answer:
he volume of the larger cube is approximately 194.52 in^3.
Explanation:
Let's denote the side length of the larger cube as x (in inches). We know that the side length of the smaller cube is 2 inches less than the side length of the larger cube, so we can write:
side length of smaller cube = x - 2
The volume of a cube is given by the formula V = s^3, where s is the side length. Therefore, the volume of the smaller cube is:
V(smaller) = (x - 2)^3
We are given that the volume of the smaller cube is 86 in^3, so we can write:
(x - 2)^3 = 86
To solve for x, we can take the cube root of both sides:
x - 2 = ∛86
x = ∛86 + 2
Now that we know the value of x, we can find the volume of the larger cube using the formula V = s^3:
V(larger) = x^3
Substituting the expression for x, we get:
V(larger) = (∛86 + 2)^3
Using a calculator, we can evaluate this expression and get:
V(larger) ≈ 194.52 in^3
Therefore, the volume of the larger cube is approximately 194.52 in^3.
