A pyramid has a volume of 18 in3. If all measures of the pyramid are multiplied by 6, what will the volume be?
guajiro [1.7K]
The formula for solving volume of a pyramid is shown below:
Volume = l*h*w / 3
18 = l*h*w/3
Originally, it is given that the volume of a pyramid is 18 inches³. If we are supposed to multiply all measurements by 6, we can attain new volume and solution is shown below:
New volume = 6³l*w*h /3
New volume = 6³ (18)
New volume = 3,888 in³


The answer is 3,888 inches³.
