Question

A beam 5m long and 40cm wide containing 0.6 cubic meters of wood. How thick is the beam?

Answer 1

for example volume is height x length x weight

so, h x l x w = .6 cubic meters

h x 5 x .4 = .6

h = .6/(5 x.4)

h/thickness = .3 m or 30 cm or 30/2.54 in or 11.8110 inches

Answer 2

Given :

A beam 5m long and 40cm wide containing 0.6 cubic meters of wood.

To Find :

How thick is the beam?

Solution:

Let the thickness of beam be x

Length of beam = 5m

Width of beam = 40 cm = 0.4 m

Volume of wood =$Length \times Width \times Thickness$

Volume of wood =$5 \times 0.4 \times x$

We are given that volume is 0.6 cubic meters of wood.

So,$5 \times 0.4 \times x=0.6$

$x=\frac{0.6}{5 \times 0.4}$

x=0.3

Hence The thickness is 0.3
