WebSurface Area = 2 (Area of top) + (perimeter of top)* height. Surface Area = 2 ( pi r 2) + (2 pi r)* h. In words, the easiest way is to think of a can. The surface area is the areas of all the parts needed to cover the can. That's the top, the bottom, and the paper label that wraps around the middle. WebTotal surface area of a rectangular prism = 2 ( 8 x 4 + 2 x 4 + 8 x 2 ) = 2 x (32 + 8 + 16 ) = 2 x 56 = 112 sq. units. Let us now find out the surface area of the rectangular prism using nets. The first step would be to unfold the given rectangular prism in the form of a net. We would obtain the following on doing so –.
WebStep 3: Demonstrate how to calculate total surface area for the rectangular prism you have drawn. The answer is 2 • (20 + 12 + 15) = 94 square feet. Step 4: Now draw a cylinder and mark the dimensions with the radius at 3 feet and the height at 4 feet. Indicate that the surface area for a cylinder equals the area of the two bases plus the ...
