The walls, ceiling and floor of a cubic room need to be painted. the edge length for the cube is 3 meters. what is the total surface area that will be painted in the room? 27 m² 30 m² 36 m² 54 m² : d

Since it is a 3-dimensional square (cube), the edge length (L) is essentially the length, width, and height. Any cube has 6 faces (4 sides/walls, a top/ceiling, and a bottom/floor). Volumes (V) and Surface Areas (SA) of cubes are quite simple:

therefore since L = 3m, then:

Yes. there is a constant ratio of number of calories to gram of protein.12/3=24/4=32/8=44/11=4
