The formula for the volume of a square pyramid is
v = (b2h) - 3, where b is the length of one side of the
square base and h is the height of the pyramid. find the
length of a side of the base of a square pyramid that has
a height of 3 inches and a volume of 25 cubic inches.

5 inches

Step-by-step explanation:

The volume of the square pyramid is given by:

where b is the length of one side of the

square base and h is the height of the pyramid.

The height is given as h=3 inches and volume, V=25 cubic inches.

We substitute and solve for b

Take principal square root to get:

inches.

Hence the length of a side is 5 inches.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
