The formula for calculating the surface area of a cuboid is


A = 2lw + 2hw + 2lh

where
l = length,
w = width,
h = height

Let's calculate


A = (2 * 6 * 2) + (2 * 5 * 2) + (2 * 6 * 5)\\A = 104m^(2)

Answer:

104 m

Explanation:

[] Surface area is the area of the surface. In other words, we will need to find the area of 6 rectangles and then add them together.

-> Since it is a rectangular prism, it will have three pairs of sides that are congruent. We can find the area of one of the sides and multiply it by two for all 6 as shown below. Then we just need to simplify.

2 (2 * 5) + 2 (6 * 5) + 2 (6 * 2)

2 (10) + 2 (30) + 2 (12)

20 + 60 + 24

80 + 24

104

104 m

[] Why is it not 60?

-> 60 is the area of the figure, not the surface area

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
