Practicing Success
The lengths, the breadths, and the volumes of two cuboids are in the ratios of 4 : 5, 3: 4, and 2 : 3, respectively. What is the ratio of their heights? |
3 : 5 10 : 9 8 : 15 2 : 3 |
10 : 9 |
We know that, Area of a cuboid = length × breadth × height We have, Ratio of the length = 4 : 5 Ratio of the breadth = 3 : 4 Ratio of the volume = 2 : 3 Now according to the question, \(\frac{4 × 3 × h}{5 × 4 × H}\) = \(\frac{2}{3}\) \(\frac{12 × h}{20 × H}\) = \(\frac{2}{3}\) \(\frac{ h}{ H}\) = \(\frac{10}{9}\) |
