Answer:
Height of the pyramid = 3v/y² units
Step-by-step explanation:
We are given;
- The volume of a solid right pyramid with a square base = v units³
- The length of the base edge = y units
The formula for volume of a pyramid is given as;
V = ⅓ x base area x height.
Since the base is square, we will use the formula for square area which is A = side × side.
Thus, v = ⅓ × (y × y) × height
Making height the subject, we have;
Height = 3v/y²
height of the pyramid would be given by the expression 3v/y² units
Answer:
30
Step-by-step explanation:
triangle ABC is proportional to triangle BCD so
hypothenuse of ABC/ ajdacent of ABC = hypotrnus BCD/ ajdacent of BCD
in short
AC/BC = BC/DC
10/x = x/3
10 . 3 = x²
x² = 30
x = √30
so the question mark is 30
