A proposed earth embankment requires 50,000 cubic meters of soil. The soil will be compacted to a void ratio of 0.75 when it is placed in the embankment. There are four available borrow pits, designated A, B, C, and D. The void ratio of the soil in each pit and the cost per cubic meter for moving the soil to the proposed construction site are shown as follows: Borrow Pit Void Ratio Cost (PhP/m³) A 0.85 450 В 1.90 250 0.95 350 0.70 550 Determine which borrow pit is the most economical.

Question
A proposed earth embankment requires 50,000 cubic meters of soil. The soil will be
compacted to a void ratio of 0.75 when it is placed in the embankment. There are four
available borrow pits, designated A, B, C, and D. The void ratio of the soil in each pit and the
cost per cubic meter for moving the soil to the proposed construction site are shown as
follows:
Borrow Pit
Void Ratio
Cost (PhP/m³)
A
0.85
450
1.90
250
C
0.95
350
0.70
550
Determine which borrow pit is the most economical.
