Step 1

The picture below shows the pyramid with the width of 2cm, length of 3cm and the height h.

Step 2

Since the values of the volume, V and width w and length l are given, we can substitute them into the volume of a pyramid formula to find h:

Step 3

Now, we have 2h = 6. To get a step closer in finding h, we need to remove 2 by dividing both sides of the equation with 2. This is shown below:

Step 4

Now, the calculated number 3, has no meaning until we include the unit for it. Since volume in unit cm³, h will be in cm. Hence:

h = 3 cm

Step 5

Therefore, the answer is D.
