Question

Use the image to answer the question.

A 4-sided pyramid with height from the top to base labeled 15 feet, the length of the base labeled 12 feet, and the width of the base labeled 6 feet.

If the above pyramid is dilated using a scale factor of 2, what would be the new volume? To find the volume of a pyramid, use V = l w h/3
.

Answer 1

Original volume = (12)(6)(15)/3 = 360 ft^3.
Scale factor = 2 ⇒ volume multiplies by 2^3 = 8.
New volume = 360·8 = 2880 ft^3.
