Step-by-step explanation:
The formula for the volume of a cube is:
V =
Where;
V = Volume
a = side
Plug the information into the formula.
V =
V =
That is the volume of one cube. If all of the cubes have the same length, in order to find the volume of the whole figure, we must count how many cubes there are and multiply that number by the volume.
If I am not mistaken, I can count 10 cubes.
10 times the Volume of one cube = Volume of the solid figure.
Therefore, the volume of the solid figure is

The second function represents an even function;
Step-by-step explanation:
A function f(x) is said to be even if f(x) = f(-x). All we need to do is replace x with -x in each equation, simplify it and assess whether the equation remains unchanged. If the equation is identical to the original one then it is said to be even. Another good example of an even function is the cosine function. Moreover, even functions have y-axis symmetry
