### Example Question #1932 : High School Math

The volume of a 6-foot-tall square pyramid is 8 cubic feet. How long are the sides of the base?

**Possible Answers:**

**Correct answer:**

Volume of a pyramid is

Thus:

Area of the base is .

Therefore, each side is .

### Example Question #51 : Solid Geometry

A right pyramid with a square base has a height that is twice the length of one edge of the base. If the height of the pyramid is 6 meters, find the volume of the pyramid.

**Possible Answers:**

6

24

18

30

12

**Correct answer:**

18

If the height, which is twice the length of the base edges, measures 6 meters, then each base edge must measure 3 meters.

Since the base is a square, the area of the base is 3 x 3 = 9.

Therefore the volume of the right pyramid is V = (1/3) x area of the base x height = 1/3(9)(6) = 18.

### Example Question #1 : How To Find The Volume Of A Pyramid

*Figure not drawn to scale*

In the pyramid above, the base is a square. The distance between points C and D is 6 inches and the length of side b is 5 inches. What is the volume of this pyramid?

**Possible Answers:**

**Correct answer:**

To find the volume of a pyramid, you need to use the equation below:

To find the height (shown by the yellow line), we can draw a right triangle using the yellow line, blue line and side b (5 inches). Because the hypotenuse is 5 inches, using the common Pythagorean 3-4-5 triple. The blue line is 3 inches and the yellow line (height) is 4 inches. Also, to find side a, we can use the blue line (3 inches) and half of the red line (3 inches) and the Pythagorean Theorum.

Because the base is a square, the area of the base is equal to the square of side a:

Now we plug in these values to find the volume:

### Example Question #2 : How To Find The Volume Of A Pyramid
