One of the managers suggests that they could cut the volume of plastic used to make the paper weights in half if they cut the side length of the base in half.

Question

is the managers reasoning correct? Explain.

 

volume=300 cubic centimeters

 

side length=10 cm

 

its a square pyrami by the way

Answer 1

If you want to calculate the volume of a pyramid, you multiply the area of the base by the volume and also by another factor of one third.

 

So you tell me: How does what you get with the shortened base compare to what you get with the original base?
