1.) use the formula sa=6s², where sa is the surface area and s is the edge length of the cube, to solve this problem. the cube has an edge length of 4 in. what is the surface area? 2.) faye bought a rug in the shape shown. what is the area of the rug? a trapezoid having to dotted lines going down to the base, the height is 6 for one of them. b2= 3, 6 and 3 are at the bottom of the trapezoid making it the base. though no b1. 3.) use the formula v=s³, where v is the volume and s is the edge length of the cube, to solve this problem. what is the volume of the cube? enter your answer as a mixed number in simplest form. (the cube shows 2 1/2)
