WebSo the diagonal of a cube is 173.2 m. Q.2. Calculate the length of the diagonal of a cube whose sides are 18 inches long. Solution: Given, the cube’s side length (a) = 18 inches, Let the body diagonal be D. Each cube’s diagonal length = √3a. After using the formula. Length of each body diagonal of cube = √3a. ⇒ √3a ⇒√3 × 18 ... WebExample 2: The space diagonal of an ice cube is 5√3 units. Find its lateral area. Solution: Method 1: Let us assume that the edge length of the ice cube is x. The space diagonal of the ice cube = 5√3 units. We know that the relationship between the side length (x) and the space diagonal (d) of a cube is expressed as, d = x √3. So, we can ...
