Question
If the volume of a cuboidal tank is 1620 m3
and the ratio of the length, width and height of tank is 5:4:3 respectively then find the height of the cuboidal tank.Solution
Let the length, width and height of tank be 5x, 4x and 3x respectively. According to the question, => 5x × 4x × 3x = 1620 => x3 = 27 => x = 3 Height of the cuboidal tank = 3x = 9 m
