Cube: As = (4 * 4)6 = 96cm^2.
Rt. Circular Cylinder:
As = (3.14r^2)2 ) + 6.28rh,
As = (3.14 * 3^2)2 + 6.28 * 3 * 12
As = 56.52 + 226.08 = 282.6cm^2.
Rt. Rectangular Prism:
As = (8 * 5)2 + (5 * 6)2 + (6 * 8)2,
As = 80 + 60 + 96 = 236cm^2.

Sphere: As = 4*3.14*r^2 = 4*3.14*2^2 =
50.3cm^2.
Rt. Circular cone:
As = 3.14r^2 + 3.14rs. s = sqrt(r^2 + h^2).
s = sqrt(64 + 36) = 10cm.
As = 3.14 * 4^2 + 3.14 * 4*10,
As = 50.27 + 125.66 = 175.9cm^2.
