Plane Geometry Answer 3:

3. A box is manufactured to contain either laptop computers or notebook computers. When the computer systems are removed from the box, it is reused to hold other items. If the length of the box is 20cm, the width is 15cm, and the height is 25cm, what is the volume of the box?

A. 150

B. 300

C. 750

D. 7500

E. 15000

The correct answer is D.

To calculate the volume of a box, you need this formula:

volume = base ´ width ´ height

Now substitute the values into the formula from the problem:

volume = base ´ width ´ height

volume = 20 ´ 15 ´ 10

volume = 7500
