To calculate the total surface area of a cuboid, you can use the formula:
\[ \text{Surface Area} = 2(lw + lh + wh) \]
where:
- \(l\) = length,
- \(w\) = width,
- \(h\) = height.
In this case, the dimensions of the cuboid are all given as 5 centimeters (since it's a cube in this case):
- \(l = 5 , \text{cm}\)
- \(w = 5 , \text{cm}\)
- \(h = 5 , \text{cm}\)
Now plug the values into the formula:
\[ \text{Surface Area} = 2(5 \times 5 + 5 \times 5 + 5 \times 5) \] \[ = 2(25 + 25 + 25) \] \[ = 2(75) \] \[ = 150 , \text{cm}^2 \]
So, the total surface area of the storage bin is:
\[ \text{Surface Area} = 150 , \text{cm}^2 \]
