Question 1081941: Two identical circular holes of diameter 12cm are drilled through a solid rectangular prism. Determine the change in surface area caused by the added holes.
The rectangular prism has a length of 36cm, width of 23cm and height of 20cm Answer by josgarithmetic(39617) (Show Source):
You can put this solution on YOUR website! Assuming the each hole is drilled through the opposing 36*23 cm^2 sides, their length each is 20 cm.
This setup is subtracting the surface which makes the holes on the opposising drilled sides and adds the surface of each cylinder.
