Answer: first option
Step-by-step explanation:
The volume of a regular pyramid can be calculated with the following fromula:
Where B is the area of the base of the pyramid and h iis the height of the pyramid.
The base is a square, therefore, its area B is:
You know that the height is 3, therefore, you can substitute these values into the formula.
THerefore, the volume of the pyramid is:
Answer:
B.
I hope it will be useful.
Hint:
Since its an isosceles right angled triangle! (Apply the properties)
Or, you can use Pythagoras theorem.
(2x^2=9 v.i.z., on rationalizing 1.5*√2)

1.) false
2.) true
3.) false
Similar means equal angles and proportional sides
Triangles can be similar by SSS, AA or SAS
Area is length times width so it is 3 times 3 since a square sides are all the same
