The base of the rectangular block is 8.0 cm 10.0 cm A circular protrusion (diameter 4.0 cm and height 3.
The base of the rectangular block is 8.0 cm × 10.0 cm
A circular protrusion (diameter 4.0 cm and height 3.0 cm) is connected to the base such that the symmetry axis is normal to the top face plane and intersects the geometric centre of the base.
There is a hole through the center of the protrusion that extends through the base to the bottom of the base. The diameter of the hole is 2.0 cm, and the depth of the hole is 5.0 cm.
There are four through-holes, one at each corner of the rectangular top face: Diameter = 0.54cm. (Note: these 4 holes go all theway through the base)
The center of each of the 4 through-holes is 0.76 cm from each edge.
Whats the surface area of the object. Please show all the steps (And an image of the object is attached with this question).
