Given a pyramid with a volume of 6cm3, width of 2cm and length of 3cm. Find the height of the pyramid.
The picture below shows the pyramid with the width of 2cm, length of 3cm and the height h.
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:
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:
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:
Therefore, the answer is D.
