### Example Question #1 : Volume Of A Pyramid

The above square pyramid has volume 100. Evaluate to the nearest tenth.

**Possible Answers:**

**Correct answer:**

The volume of a square pyramid with base of area and with height is

.

The base, being a square of sidelength , has area . The height is . Therefore, setting , we solve for in the equation

### Example Question #1611 : Ged Math

A square pyramid whose base has sidelength has volume . What is the ratio of the height of the pyramid to the sidelength of its base?

**Possible Answers:**

**Correct answer:**

Since the correct answer is independent of the value of , for simplicity's sake, assume that .

The volume of a square pyramid with base of area and with height is

.

The base, being a square of sidelength 1, has area 1. In the volume formula, we set and , and solve for :

This means that the height-to-sidelength ratio is equal to , which is the correct response.
