Answer
The cost of the paint will be 8.00 dollars.
Work Step by Step
The area of the surface for 1 rectangular piece of wood can be found by using the formula: A = l $\times$ W
Substitute 0.6 for l and 0.3 for w to obtain:
A = 0.6 $\times$ 0,3 = 0.18 square meters.
Since we have 50 wood pieces, the total area to be painted is:
0.18 $\times$ 50 = 9 square meters
Since 1 liter costs 8.00 and covers exactly 9 square meters, the cost of the paint will be 8.00 dollars.
