A wooden beam is $ 8 \mathrm{~m} $ long and 2 m wide contains 1280 cubic metres of wood. What is the thickness of the beam?

Given:

Length of the beam $=8\ m$

Width of the beam$=2\ m$

The beam contains 1280 cubic metres of wood.

To do:

We have to find the thickness of the beam.

Solution:

Let the thickness of the beam be $x$.

Volume of the beam$=$The amount of wood the beam contains

This implies,

$8\times2\times x=1280$

$x=\frac{1280}{16}$

$x=80\ m$

The thickness of the beam is $80\ m$.
