1/9 of the larger triangle's area is unshaded. That means the linear (edge) dimension of the smaller shaded triangle is 1/3 of the edge dimension of the larger triangle. The perimeters of the two triangles will also be in a large:small = 3:1 ratio.

Which of the following is a formula for finding the volume of a cube? A. v=e^3, where e= the edge length B. v=(lwh)^3, wherel= length,w=width andh=height C.v=6e^2, where e=the edge length D. v=b*b, where b= the area of the base I picked A since V=s^3 or e^3 for the volume of a...
