The absolute value, or modulus, of a number is its distance from zero, or essentially its magnitude.
The absolute value produces a positive answer.
We have this definition for the absolute value, taking into account its different values for different signs:

Thus, for

, we split the absolute value as such:

and

We solve each case.

and

We check these solutions.

Okay let h be the height of prism
so ATQ, height of pyramid = 3h
put this in the formule
The volume of a pyramid = base x height x (1/3)
The volume of a prism = base x height
and find their ratio so simple
you will get the answer as 1
Answer:
b = √45
Step-by-step explanation:
From the figure we get, There are two right angled triangle.
In large triangle 'b' is the base, height = 6 and hypotenuse = 9
<u>To find the value of b</u>
Hypotenuse² = Base² + Height²
Here,
9² = b² + 6²
b² = 9² - 6² = 81 - 36 = 45
Therefore, b = √45
