Final answer:
The surface area of the cube that Nia receives with each side being 1 foot long is 6 square feet.
Step-by-step explanation:
Nia receives a package in the shape of a cube where each side of the cube is 1 foot long. To find the surface area of the cube, we use the surface area formula for cubes, which is SA = 6s², where s represents the length of a side of the cube. Plugging in the side length of 1 foot into the formula, we get:
SA = 6(1 foot)²
SA = 6(1 foot × 1 foot)
SA = 6 square feet
So, the surface area of Nia's package is 6 square feet.
