the base of rectangular prism has a length of a m and a width of 4 m. if the volume is 64 cubic meters, what is the height of the prism?

Volume of any right prism is
1/3 areabase*height
64= 1/3 l*w*h
solve for height. 
Your school subject is NOT altgeld.
Use this formula:
Volume = length * width * height.
