A rectangular solid has sides of 7 cm + 9 cm + 11 cm what is its surface area

alina1380 [7]

Your answer would be: 693.

Explanation:

When finding the area in a problem use L×W×H.

That being said, you now have to multiply the L×W×H (7x9x11)

7 × 9 × 11 = 693

So the answer would be 693 because, if you are finding an area you use L×W×H to find your area.

Rule for raising a power to a new power

KiRa [710]

The practical rule would be, times that number, by the result of the first time you multiplied the first number. But, it would all depend by how much your're raising the number by.

For example: $\boxed{4^6}$

We do, $(4*4*4*4*4*4)= \boxed{\bf{4^6}}= 4096$

But, once again, this was an example. This would show and illustrate the rule of "raising a power".
