Answer:

148cm²

Step-by-step explanation:

With the first frontal face of the cuboid, you have length 6 cm whilst the height remains 5 cm.

Find the area of this face and multiply the result by 2, as there are two of these faces (front and back)

6 x 5 = 30 cm²

30 x 2 = 60cm²

Do the same with the top face and bottom face, adding this with the side faces

4 x 6 = 24cm²

24 x 2 = 48cm²

4 x 5 = 20cm² x 2 = 40 cm²

40 + 48 + 60 = 148 cm²

T.S.A = 148cm²

Step-by-step explanation:

<h3>
What is Range?</h3>

- Range is a set of all y-values in a set of coordinate points.

<h3>
Consider This:</h3>

A linear equation or function always have range equal to set of real number because you can substitute f(x) as any numbers and you'll still be able to solve for x-variable.

An quadratic equation or function may have range equal to set of positive real number or negative real number depending whether if the coefficient of x² is in positive or negative but consider this:

Suppose we have f(x) = x², f(x) cannot be negative number because that'd make the equation not real. Therefore, a quadratic function does not have $\displaystyle{\mathbb{R}}$ range.

For an exponential function, it's same as quadratic equation. It depends whether if a base is in negative or positive. You can consider like this:

Suppose we have $\displaystyle{f(x)=2^x}$ , f(x) cannot be negative number because there are no x-values that make the equation true. Therefore, an exponential function does not have $\displaystyle{\mathbb{R}}$ range as well.
