The volume of a cube is 3375 cm3. What is the length of the longest rod that can be placed in this cube? |
15 cm 15$\sqrt{3}$ cm 45 cm 12$\sqrt{3}$ cm |
15$\sqrt{3}$ cm |
We know that, The volume of cube = side3 Diagonal of cubes = \(\sqrt {3}\) × Side of cube We have, The volume of cube = 3375 cm3 = side3 = 3375 cm3 = side = 15 cm length of the longest rod = \(\sqrt {3}\) × Side of cube = 15\(\sqrt {3}\) cm |
