Answer: The surface area of the cuboid is 60 square units.
Explanation:
A cuboid is a three-dimensional shape having six rectangular faces. To find the surface area, sum the areas of all six faces. So let's split it down:
The front and back faces are rectangles, and their area may be calculated by multiplying the length by the width. So the front and back face areas of our cuboid will be 2.5 x 6 = 15.
The top and bottom faces are also rectangles with an area of 6 x 5 = 30.
The left and right faces are rectangles with an area of 2.5 x 5 = 12.5.
Now add all of these regions together to get the total surface area: 15 + 30 + 12.5 + 12.5 = 60
