Alex needs to varnish the top And the bottom of a dozen rectangular wooden planks planks are 8 feet long and 3 feet wide each pi

meriva

Answer:

It will cost approximately $16.12 to varnish all the wooden planks.

Step-by-step explanation:

We are given the following in the question:

Number of rectangular planks = 12

Dimension of the rectangular wooden plank:

Length = 8 feet

Width = 3 feet

Area covered by I bottle of varnish = 125 Square feet

Cost of 1 bottle of varnish = 3.50 units

Area of 1 rectangular plot =

$A = \text{Length}\times \text{Width}\\A = 8\times 3\\A = 24\text{ square feet}$

Total area to be covered by varnish =

$= \text{Area of 1 plank}\times 12\times \text{Top area and bottom area}\\=24\times 12\times 2\\=576$

Number of varnish bottles required =

$n = \dfrac{\text{Total area}}{\text{Total area covered by 1 varnish bottle}} = \dfrac{576}{125} = 4.608$

Cost of varnishing =

$=\text{Cost of 1bottle of varnish}\times \text{Number of varnish bottles}\\=4.608\times 3.50\\=\$16.12$

Thus, it will cost approximately $16.12 to varnish all the wooden planks.
