Density = mass / volume So if we know the density and volume, make an algebraic equation of this. 4.1 = m ÷ 2.3 Multiply each side by 2.3. 9.43 = m The mass is 9.43 grams, hope this helps!
You have to use the formula to find the area of the triangle Remember,the area equation is b times h to the b divided by 2.Doing this will get you 600 m.
