The surface area of a rectangular solid (also known as a rectangular prism) can be calculated using the formula:
Surface Area = 2(lw + lh + wh)
where l is the length, w is the width, and h is the height.
In this case, we have:
- Length (l): 10 cm
- Width (w): 6 cm
- Height (h): 8 cm
Now we can substitute these values into the formula:
Surface Area = 2(10 * 6 + 10 * 8 + 6 * 8)
Calculating each part:
- 10 * 6 = 60
- 10 * 8 = 80
- 6 * 8 = 48
Now, adding these values together:
60 + 80 + 48 = 188
Then, multiplying by 2:
Surface Area = 2 * 188 = 376 cm²
So, the surface area of the rectangular solid is 376 cm².
