Question

One gallon of paint (volume = 3.79 X 10-???? m3) covers an area of 25.0 m2. What i the thickne s of the fresh paint on the wall?

Answer 1

Step-by-step explanation:

Given

Volume of paint is
`V=3.79* 10^(-3)\ m^3`

Area of cover
`A=25\ m^2`

Suppose paint to be a rectangular box with thickness t and volume V

therefore we can write as

`V=A* t`

`t=(V)/(A)`

`t=(3.79* 10^(-3))/(25)`

`t=1.516* 10^(-3)\ m`

`t=1.516\ mm`
