Keenan wants to make a paperweight at pottery class. He designs a pyramid-like model with a base area of 80 square centimeters and a height of 7.5 centimeters. The density of the clay he is using is 1.7 grams per cubic centimeter. What is the weight of Keenan’s paperweight?

Weight of project: 340 grams

Step-by-step explanation:

It's a simple geometry problem to be honest. So you want to start off with the equation for the volume of a pyramid which is 1/3BH where B=Base and H= Height.

So it should look like this 1/3(80)(7.5)= 200cm 2 x 7.5g = 340 Grams

faster, im not sure why but i know it is faster
