Answer:
We will need 16 tiles
Step-by-step explanation:
Each tile has a width of 1/4 ft
We want to know how many will fill 4 ft
This is a division problem
4 ft wall/ 1/4ft tiles =

The height of the triangular base of the pyramid is calculated through the equation,
h = (cos x)(18 in)
where h is height and x is half of the angle of the triangle. Since the triangle is equilateral, the value of x is 30°. Substituting,
h = (cos 30°)(18 in)
h = 15.59 in
Thus, the height of the base is approximately 15.59 inches.
Confusing to me, sorry i cant help. I am not good with graphs.
