Alec used 8 cubes to make this square frame that has 3 cubes on each side. If he uses 16 cubes to make a square frame, how many cubes will be on each side of the frame
Draw a diagram, first of 8 cubes with 3 on each side. Then draw a diagram with 16 cubes.
well, I can make a square face 3 on an edge with 9 cubes but I have some trouble with 8. I could make a cube with 8 cubes though. I could also make a square frame with 4 on an edge with 16 cubes
Find the surface area of this rectangular prism
