Steps of construction:
a)Draw AC = 8cm.
b)Draw perpendicular bisector XY of AC meeting AC at O.
c)From O cut off OD = ×6 cm = 3 cm along OX and OB = ×6 cm =3 cm along OY.
d)Join AB, BC, CD, and DA.
ABCD is the required rhombus
Note that the scale factor of B to A is (4 / 8) = 1/2
So....the volume of B =
Volume of A * (scale factor)^3 =
2720 * (1/2)^3 =
2720 * 1/8 =

Answer C
6 triangles around. 1/2bh=. 1/2 (15)(12)(6) triangles = 540
Bottom base formula 1/2 a p
1/2 (7.5 sq rt of 3)(15)(6)= 584.56
1,124.56
1,125
