Answer:
d. ![8\text{ ft}^3](https://tex.z-dn.net/?f=8%5Ctext%7B%20ft%7D%5E3)
Step-by-step explanation:
We have been given that Cheng measures each edge of each base to be 2 feet. The height of the whole sculpture is 6 feet.
First of all, we will find height of each pyramid by dividing height of whole sculpture by 4 as:
![\frac{6\text{ ft}}{4}=1.5\text{ ft}](https://tex.z-dn.net/?f=%5Cfrac%7B6%5Ctext%7B%20ft%7D%7D%7B4%7D%3D1.5%5Ctext%7B%20ft%7D)
We know that volume of a pyramid is equal to 1/3 of base area times height that is
, where b represents area of base.
![V=\frac{(2\text{ ft})^2\times\text{ 1.5 ft}}{3}=4\times 0.5\text{ ft}^3=2\text{ ft}^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B%282%5Ctext%7B%20ft%7D%29%5E2%5Ctimes%5Ctext%7B%201.5%20ft%7D%7D%7B3%7D%3D4%5Ctimes%200.5%5Ctext%7B%20ft%7D%5E3%3D2%5Ctext%7B%20ft%7D%5E3)
Since volume of one pyramid is equal to 2 cubic feet, so volume of 4 pyramids will be 4 times 2 cubic feet that is 8 cubic feet.
Therefore, Cheng must purchase 8 cubic feet of material.
$44 is equal to the original price [P] take away 20% or 0.20 of the original price
![44=P-0.20P](https://tex.z-dn.net/?f=44%3DP-0.20P)
44 = 0.80*P
In other words, 44 is 80percent of the original price P
P = 55
Procedure:
1) Integrate the function, from t =0 to t = 60 minutues to obtain the number of liters pumped out in the entire interval, and
2) Substract the result from the initial content of the tank (1000 liters).
Hands on:
Integral of (6 - 6e^-0.13t) dt ]from t =0 to t = 60 min =
= 6t + 6 e^-0.13t / 0.13 = 6t + 46.1538 e^-0.13t ] from t =0 to t = 60 min =
6*60 + 46.1538 e^(-0.13*60) - 0 - 46.1538 = 360 + 0.01891 - 46.1538 = 313.865 liters
2) 1000 liters - 313.865 liters = 613.135 liters
Answer: 613.135 liters
