Given that the volume of the prism is given by: 10 cubic units and the the side length of cubes to fill the prism is 1/2 units. Then the number of cubes required to fill the prism will be given by: (volume of rectangular prism)/(volume of cube) but volume of cube is: volume=length*width*height volume=1/2×1/2×1/2=1/8 cubic units thus the number of cubes required to fill the prism will be: 10/(1/8) =10×8/1 =80 cube Answer: 80 cubes
The problem gives you the distance and the ammout of time this distance was traveled in. so you divide the distiance by the time and it will give you the answer
