You're uncle is having a new roof installed in his house. The roof is a square pyramid. The side length of the base of the roof is 28 foot. The volume of the roof is 18929.3333 cubic feet what is the height of the roof

The height of the roof in his house is 72.43 ft.

Step-by-step explanation:

The volume of square pyramid is :

B= area of the base.

h= the height.

Given that,

The roof is a square pyramid in shape. The volume of the roof is 18929.333 cubic feet.

The side length of the base of the roof is 28 feet.

Since the base of the roof is square in shape.

The area of the square is = side²

The area of the base is =(28×28) square feet

                                       =784  square feet

Assume the height of the roof be h ft.

Then, the volume of the roof is =

                                                    square feet.

According to the problem,

ft.

The height of the roof in his roof is 72.43 ft.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
