Therefore all faces are congruent. 5.7 i… Get the answers you need, now! \(\displaystyle x = y = z \implies x^2 + y^2 + z^2 = x^2 + x^2 + x^2 = WHAT?\) RD Sharma Solutions for Class 8 Chapter 21 Mensuration - II (Volumes and Surface Areas of a Cuboid and a Cube) Exercise 21.4 is provided here with miscellaneous problems related to the whole chapter. Therefore the length of the longest diagonal of an n -cube of side length m is m � n, and the dimension appears under the square root sign. Now the surface area is (side) x (side) x 6 faces. The length of the diagonal of the cube is 3√(a) and The lateral surface area of a cube = 4 a 2. $\sqrt {5}$ 4. toppr. 5. What would the length of each diagonal of a cube that is 45 cm on each side be? • Given a pyramid with width 24 cm, length 36 cm and height 72 cm. I drew a sketch of a cube with sides of length 4 and labeled some vertices so that A and B are in the position that you describe. So the answer is 10√3 cm. The length of the longest side equals the length of the shortest side; the length of the longest diagonal equals the length of the shortest diagonal.
