A rectangular solid has sides of 6 cm, 8 cm, and 10 cm. What is its surface area?

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.
