A pyramid has a base with a demension 5 inches by 7 inches .The height of the pyramid is unknown .If the volume of the pyramid i
Ulleksa [173]

Answer:

9 inches

Step-by-step explanation:

The volume of a pyramid is given as:

V = \frac{l* w*h}{3}

where l = length of base of pyramid

w = width of base of pyramid

h = height of pyramid

The volume of the cylinder is already known ( 105 in^3 ) and the other two dimensions are known as 5 in and 7 in.

From the formula of the volume of the pyramid, the height of the pyramid is given as:

h = \frac{3V}{l*h}

Hence, the height of the pyramid is:

h = \frac{3 * 105}{5 * 7}\\ \\h = \frac{315}{35} = 9in

The pyramid's height is 9 inches.
