Question

Keenan wants to make a paperweight at pottery class. He designs a pyramid-like model with a base area of 808080 square centimeters and a height of 7.57.57, point, 5 centimeters. The density of the clay he is using is 1.71.71, point, 7 grams per cubic centimeter.

What is the weight of Keenan's paperweight?

Answer 1

340

Explanation:

The volume of the pyramid-like paperweight is 1/3 * 80 * 7.5= 200

Now we can plug density=1.7, total quantity=w and volume=200 in the equation.

1. 1.7= w/200
2. 200 * 1.7= w
3. 340= w
