Solution

To find the volume of the cube, we need to follow these steps:

  1. Determine the surface area of one face of the cube: The surface area of a cube is given by the formula 6a26a^2, where aa is the length of one side of the cube. Given that the total surface area is 47,526 square units, we can set up the equation: 6a2=47,526 6a^2 = 47,526

  2. Solve for a2a^2: Divide both sides of the equation by 6 to isolate a2a^2: a2=47,5266 a^2 = \frac{47,526}{6} a2=7,921 a^2 = 7,921

  3. Solve for aa: Take the square root of both sides to find aa: a=7,921 a = \sqrt{7,921} a=89 a = 89

  4. Calculate the volume of the cube: The volume VV of a cube is given by the formula a3a^3. Using the value of aa we found: V=893 V = 89^3 V=89×89×89 V = 89 \times 89 \times 89 V=704,969 V = 704,969

Therefore, the volume of the cube is 704,969 cubic units.
