To find the volume of the box, multiply its length, width, and height together:

Volume = Length × Width × Height Volume = 4 feet × 4 feet × 2 feet Volume = 32 cubic feet

To find the surface area of the box, you need to calculate the areas of all six faces and then add them together:

Surface Area = 2(Length × Width) + 2(Width × Height) + 2(Length × Height) Surface Area = 2(4 feet × 4 feet) + 2(4 feet × 2 feet) + 2(4 feet × 2 feet) Surface Area = 2(16 square feet) + 2(8 square feet) + 2(8 square feet) Surface Area = 32 square feet + 16 square feet + 16 square feet Surface Area = 64 square feet

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
