Answer:
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
