Erica decides to paint the birdhouse. She has a pint of
paint that covers 32.5 ft2 of surface. How can you tell that Kali has
enough paint without calculating?
If the birdhouse is a cube that is 2 ft on each edge, the surface area is 6×2² = 24 ft². That's a pretty large birdhouse, and it will need about ¾ of a pint of paint.
