<h2>
The volume of the pyramid would be 4500 cm³.</h2>
Step-by-step explanation:
Formulas you would be using:
Volume of a pyramid: 
b = base, h = height
Area of a trapezoid: 
a = base₁ , b = base₂ , h = height
First, we're going to find the area of the trapezoid, which is the base of the pyramid.
We are given that a = 20, b = 30, h = 20
Plug it in:
= 500 cm²
Now that we have found the base of the pyramid, we can plug it in along with the height of the pyramid.
= 4500 cm³

The inverse of the given function 3x - 12 is determined as f⁻¹(x) = x/3 + 4.

What is inverse of a function?</h3>
An inverse of a function is a function that serves to replace another function.
That is, if f(x) produces y, then putting y into the inverse of f produces the 0ut-put x .
Thus, an inverse function or an anti function is defined as a function, which can reverse into another function.
The inverse of the given function; f(x)= 3x − 12 is calculated as follows;
y = 3x - 12
replace y with x and x with y as shown below;
x = 3y - 12
now, solve for y
x + 12 = 3y
divide both sides of the equation by 3
x/3 + 12/3 = 3y/3
x/3 + 4 = y
f⁻¹(x) = x/3 + 4
Thus, the inverse of the given function 3x - 12 is determined as f⁻¹(x) = x/3 + 4.
