Suppose that the measure of the base and the top is 1ft^2 and the 4 sides are 2ft^2.
Since 1ft^2 = Php 10, then we can know how much it cost totally.
Top = 1ft^2
Bottom = 1ft^2
Php 10/ft^2 (1 Top and 4 sides)
Php 20/ft^2 (1 Bottom)
1 x 10 = 10
Php 10 for top
1 x 20 = 20
Php 20 for bottom.
Now for the sides
4 Sides, 2 ft^2 of measure.
4 x 2 = 8
8 x 10 = 80
Php 80
Total of Php 110
