Find the surface area plz
vladimir1956 [14]
Hi again! ;)

If we want to find the surface area of a cube, we need to find the area of one surface first, and then multiply that by 9, since there are 9 sides/surfaces on a cube.

Since each side of a square is the same, we first find the area of one surface:

9 × 9 = 81

Then, to find the surface area, we multiply 81 by 6:

81 × 6 = 486

The surface area is
486 \:  {in}^{2}

Given that f(x) is a function that represents number of hours required to travel, the domain of the function is: distance travelled in miles (x)

<em><u>Recall:</u></em>

  • In a relation that is a function, the domain of the function is the set of input values (x-values).
  • The range of the function is the set of output values (y-values or f(x)).

Thus, given that f(x) is a function that represents number of hours required to travel, therefore:

  • x = input values (domain) = distance travelled in miles
  • f(x) = output values (range) = number of hours.
