Question

The height of a wall is six times its width and the length of wall is seven times its heigh. If the volume of the wall be 16128 m cube. Then find its width

Answer 1

Let width be x.

So height is equal to 6x and length be 7*6x = 42x.

Since Volume = 16128 m^3

=) x * 6x * 42 x = 16128 m^3

=) x^3 = 16128 m^3/ 6*42

=) x^3 = 64 m^3

=) x = 4m.

Hence width is equal to 4m.
