Slant height formula class 9
WebJan 18, 2024 · If we take the length of the cuboid as ℓ, breadth as b and the height as h, then Surface area of a cuboid = 2 [lb + bh + hl] The cuboid whose length, breadth and height are equal is called a cube. Let each edge of the cube be ‘a’, then Surface area of a cube = 6a 2. Formula for Cuboid. Curved Surface Area for Cuboid or Area of four walls ... WebLet the slant height = x inches. Substituting the values in the surface area of the cone formula, Total surface area of cone = πr (r + l) = (22/7) × 7 × (7 + x) = 616 ⇒ 22 × (7 + x) = 616 ⇒ 7 + x = 28 ⇒ x = 21 inches Answer: The slant height of cone is 21 inches.
