A Math Trick—Finding the Unknown

To use the formula triangle, start by covering the quantity you want to find.

Looking for Density?

You’re left with mass over volume, so density = mass/volume, just as we expect.

Looking for Mass?

Density next to volume is left, so mass = density x volume.

What Is a Force?

non-contact



Measuring Force



Underwater dams are built much thicker at the bottom than at the top

due to the increase in water pressure at the bottom.

water pushing on dam

dam transmits force down to base
