Final answer:
To find the total surface area of the cube-shaped planter, we need to find the area of each side and then add them together. Since all sides of a cube are equal, we can find the area of one side and then multiply it by 6. The correct answer is c. 72 square inches.
Step-by-step explanation:
The cube-shaped planter has six equal sides. To find the total surface area of the cube, we need to find the area of each side and then add them together. Since all sides of a cube are equal, we can find the area of one side and then multiply it by 6. If Amy covered the sides of the cube-shaped planter, she covered the total surface area of the cube. Therefore, the answer is total surface area, which is 6 times the area of one side.
Let's say each side of the cube planter has a length of x inches. The area of one side is x * x = x^2 square inches. Since there are 6 equal sides, the total surface area of the cube is 6 * x^2 square inches.
Now, let's look at the options given:
- a. 54 square inches: This is unlikely, as it is not a multiple of 6 (since we multiply the area of one side by 6 to get the total surface area).
- b. 24 square inches: This is also unlikely, as it is a small number for the surface area of a cube.
- c. 72 square inches: This is the correct answer, as it is 6 * 12 square inches.
- d. 36 square inches: This is unlikely, as it is half of the correct answer.
Therefore, the correct answer is c. 72 square inches.
