I need to find the height of a rectangle prism the measurments are the area of base =20 sq. cm and the volume is 40 cm3
The volume of a rectangular prism is v=lwh
We are given the area of the base which takes care of the length and width so now we have,
$\displaystyle 40cm^3=20cm^2*h$
So to isolate the height we divide both sides by $\displaystyle 20cm^2$ which gives us,
$\displaystyle \frac{40cm^3}{20cm^2}=h=2cm$
