What is the volume of a pyramid whose base is a square of area 36 and whose four faces are equilateral triangles?
irina1246 [14]

Answer:

V = 36\sqrt{2}

Step-by-step explanation:

The volume of a pyramid is

V = \dfrac{1}{3}Bh

where B = area of the base, and h = height of the pyramid

The base is a square.

A = s^2

s = \sqrt{A}

s = \sqrt{36}

s = 6

The side of the base has length 6. Each face of the pyramid is an equilateral triangle with side of length 6.

An altitude of this triangle measures

a = \sqrt{6^2 - 3^2}

a = \sqrt{27}

The pyramid is formed by 4 equilateral triangles whose bases form a square. The tips of the faces meet at a single point on top. The vertical distance from that point to the center of the base is the height of the pyramid.

h = \sqrt{(\sqrt{27})^2 - 3^2 }

h = \sqrt{27 - 9}

h = \sqrt{18}

h = 3 \sqrt{2}

Volume of the pyramid:

V = \dfrac{1}{3}Bh

V = \dfrac{1}{3}(36)(3\sqrt{2})

V = 36\sqrt{2}

When ryan is 10, his brother kyle is 15. When ryan is 16, kyle will be 21. When ryan is 21, kyle will be 26. Write and solve an
Rudik [331]
Your Equation would be X+5=y. Let X represent Ryan's age and Y represent Kyle's age. When you plug in 52 as X, your equation would be 52+5=y. Then you would simplify. 52+5=57. So when Ryan is 52, Kyle will be 57.
