Question

Edith wants to make a paperweight at pottery class. She wants the paperweight to have a pyramid-like shape with a base area of 120120120 square centimeters, and she wants it to weigh 400400400 grams. The density of the clay she is using is 1.61.61, point, 6 grams per cubic centimeter.

What should be the height of the paperweight?

Answer 1

Explanation:

We would determine the volume of the

pyramid-like paperweight. Formula for volume is expressed as

Volume = mass/density

From the information given,

mass = 400g

Density = 1.61g/cm³

Volume = 400/1.61 = 248.45cm³

The formula for determining the volume of a pyramid us expressed as

Volume = 1/3 × base area × height

From the information given,

Base area = 120 cm²

Volume = 248.45cm³

Therefore,

248.45 = 1/3 × 120 × height

248.45 = 40 × height

height = 248.45/40 = 6.2 cm
