Answer:
Step-by-step explanation:
Using k as the constant of proportionality.
The expression that expresses the relationship : p varies jointly with the square of d and the cube of u.
Varies jointly means that p will change as 'd' and 'u' will change together with respect to their powers.
We get the expression as:
Answer:
<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
Hope this helps :D
