**Visualising solid shapes class 8 Important formulas**

**Surface Area of Cube:**The surface area of a cube is equal to six times the area of one face. So, if the length of one side of the cube is 'a', then the surface area of the cube will be 6a².**Volume of Cube**: The volume of a cube is equal to the cube of its side length. So, if the length of one side of the cube is 'a', then the volume of the cube will be a³.**Surface Area of Cuboid**: The surface area of a cuboid is equal to twice the sum of the areas of its adjacent faces. So, if the length, breadth, and height of the cuboid are 'l', 'b', and 'h' respectively, then the surface area of the cuboid will be 2(lb + bh + hl).**Volume of Cuboid:**The volume of a cuboid is equal to the product of its length, breadth, and height. So, if the length, breadth, and height of the cuboid are 'l', 'b', and 'h' respectively, then the volume of the cuboid will be lbh.**Surface Area of Cylinder**: The surface area of a cylinder is equal to the sum of the areas of its curved surface and two circular bases. So, if the radius of the cylinder is 'r' and the height of the cylinder is 'h', then the surface area of the cylinder will be 2πrh + 2πr².**Volume of Cylinder:**The volume of a cylinder is equal to the product of the area of its circular base and its height. So, if the radius of the cylinder is 'r' and the height of the cylinder is 'h', then the volume of the cylinder will be πr²h.**Surface Area of Cone**: The surface area of a cone is equal to the sum of the area of its curved surface and the area of its circular base. So, if the radius of the base of the cone is 'r' and the slant height of the cone is 'l', then the surface area of the cone will be πr² + πrl.**Volume of Cone:**The volume of a cone is equal to one-third of the product of the area of its base and its height. So, if the radius of the base of the cone is 'r' and the height of the cone is 'h', then the volume of the cone will be 1/3 πr²h.Visualising solid shapes class 8 Extra Questions and Answers

**Find the surface area and volume of a cube whose side measures 5 cm.**Solution: Given, the side of the cube = 5 cm Surface area of cube = 6a² = 6 × 5² = 150 cm² Volume of cube = a³ = 5³ = 125 cm³

**Find the surface area and volume of a cuboid with dimensions 4 cm, 6 cm, and 8 cm.**Solution: Given, the dimensions of the cuboid are l = 4 cm, b = 6 cm, and h = 8 cm Surface area of cuboid = 2(lb + bh + hl) = 2(4×6 + 6×8 + 8×4) = 2(24+48+32) = 208 cm² Volume of cuboid = lbh = 4×6×8 = 192 cm³

**Find the surface area and volume of a cylinder whose radius is 7 cm and height is 10 cm.**Solution: Given, the radius of the cylinder is r = 7 cm and height is h = 10 cm Surface area of cylinder = 2πrh + 2πr² = 2π(7×10) + 2π(7²) = 440π + 98π = 538π cm² Volume of cylinder = πr²h = π(7²)×10 = 490π cm³

**Find the surface area and volume of a cone whose base radius is 4 cm and height is 6 cm.**Solution: Given, the radius of the cone is r = 4 cm and height is h = 6 cm Surface area of cone = πr² + πrl = π(4²) + π(4×√(6²+4²)) = 16π + 20π = 36π cm² Volume of cone = 1/3 πr²h = 1/3 π(4²)×6 = 32π/3 cm³
