You are missing one unit (10 ft or 10 inches). Convert all inch measurements into feet ( 1in =1/12 ft) then perform the calculation. The result will be in cubic feet.

Multiply 9ft by 2ft by 2ft to get 36 cubic feet. One foot is exactly 0.3048 meters so one cubic foot is about 0.0283 cubic meters. Multiply that by 36 to get about 1.019 cubic meters.

Here is the basic knowledge to help find your answer

**1inch=2.54 cm**

**1cm=0.01 m**

1foot=12 inches=12*2.54 cm=30.48 cm=0.3048 m

Volume of timber =**2*2*9 *(0.3048)^3 **m^3=1.019 steres

1foot=12 inches=12*2.54 cm=30.48 cm=0.3048 m

Volume of timber =

A yard is 1 dimensional so just a straight line.

A cubic yard is 3 dimensional so imagine a box with all sides being 1 yard long, the volume of this box is a cubic yard.

We find volume by using V = H*W*L , where H = height , W = width, and L = length. You say H = 2 ft,

V = 80 ft ^3, and W = L - 3 . Put all of these back onto the equation and we will have

80 = 2 * (L - 3) * L . We can condense this to be 80 = (2*L - 2*3 ) * L then becomes 80 = 2*L*L - 2*3*L

simplifying this we get 40 = L*L - 3*L . This is also 40 = L * (L - 3) this is a quadratic equation, meaning that

we will get two answers for L. In this case L = 0 and L = 3. Since 0 ft would mean that the tool box doesn't

have a length we will use L = 3. We can now put this back into our original equation to find out what the

width is. 80 = 2 * W * 3, this is 80/6 = W = 13.3333 . Now we know that W = 13.3333 and L = 3.

- You cannot convert square meters (m²) to meters (m). The first unit measures an area, the second a length. You might as well ask, "what is the weight of two hours".
- There is no single answer without further constraints given. Even assuming a box-shaped room, it might be, for example 1ft x 1ft x 300,000ft or 100ft x 100ft x 30ft. Infinite more combinations are possible.
- My pleasure ;-)
