Question

the volume of a rectangular box is 480 cubic cm if the ratio of its length width to height is 3:4:5 find the length of the rectangular box

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

Length is $6cm$.

Step-by-step explanation:

It is given that the volume of rectangular box is $480cm^{3}$.

Ratio of length, width to height is $3:4:5$

Since the volume is given, it cannot be rectangle, here we are taking about cuboid.

A cuboid is defined as a hexahedron, a six-faced solid and its faces are quadrilateral.

Volume is quantity expressing the total amount of three dimensional space enclosed by a closed surface. It is calculated for three dimensional figures.

Let length $l=3x$

breadth $b=4x$

Height $h=5x$

Volume is $60x^{3} =480$

$x=2$

So, length $l=3x=3*2=6cm$
