Find the area of the dining room in square feet. round to nearest square foot.
8"x 10"x 8"

Surface Area of the room = 448 units²

Step-by-step explanation:

The dimensions of the room are given to be : 8" x 10" x 8"

Since, The room is cuboid in the shape

Therefore, Length of the room, l = 8 units

Width of the room, w = 10 units

Height of the room, h = 8 units.

Now, we need to find the surface area of this given room.

Surface Area of cuboid is given by the formula : 2 × (l·w + w·h + h·l)

Thus, Surface Area of the room = 2 × (8 × 10 + 10 × 8 + 8 × 8)

⇒ Surface Area of the room = 2 × (80 + 80 + 64)

⇒ Surface Area of the room = 2 × 224

⇒ Surface Area of the room = 448 units²
