WebArea is the size of a two-dimensional surface. It is defined as the amount of two-dimensional space occupied by an object. Area formulas have many practical applications in building, farming, architecture, science. The area of a shape can be determined by placing the shape over a grid and counting the number of squares that covers the entire … WebStep 4: The fourth step is to calculate the base area of the cylinder. Base area of cylinder = π r 2 = (22 7) × 0.7 2 = 1.54 c m 2 Step 5: The final step is to calculate the surface area of the resultant solid. This can be found out by: Surface area of solid = CSA of Cylinder + CSA of Cone + base area of cylinder = 10.56 c m 2 + 5.5 c m 2 + 1 ...

WebThe surface area is the area of one face of a solid exposed in a three-dimensional plane. The total surface area is the sum of the area of all the surfaces of the solid. For example, a cube has 6 faces, so its total surface area will be 6 times the surface area of one face. WebThe total surface area of solid = Area of 5 sides of cube + CSA of Hemisphere + Face area remaining after the hemispherical part is removed. Area of 5 sides of the cube is 5a² = 5 × 7 2 = 245 c m ². CSA of hemisphere
