HELP PLEASE METAL + FAN <<<<<<< !!

A wooden pyramid, 9 inches tall, has a square base. A carpenter increases the dimensions of the wooden pyramid by a factor of 4 and makes a larger pyramid with the new dimensions. Describe in complete sentences the ratio of the volumes of the two pyramids.

Answer 1

a simple method is to find the volume of a pyramid with base length 1 inch and height 9 inches.

So if the dimensions are increased by a factor of 4 multiply the measurements in the previous part by 4 and find the volume... this will allow you to compare the volumes and make a conclusion about the ratio of volumes.

Answer 2
