Answer:
The options are given below:
a. $24.00
b. $8.00
c. $6.24
d. $18.72
The correct option is c.
Step-by-step explanation:
For this problem, we will first solve for the volume as follows:
Volume = [tex]\frac{lwh}{3}[/tex]
where:
l = length
w = width
h = height
therefore:
V = [tex]\frac{2X2X 6}{3}[/tex]
V = [tex]\frac{24}{3}[/tex]
V= 8ft^3
Now we calculate the cost of filling the pyramid:
Since 1ft^3 cost $0.78
Then 8ft^3 will cost = 8 X 0.78 = $6.24
