This is the concept of volumes of solid figures;
To calculate for the volume of material required we calculate for the volume of the pyramid;
volume of the pyramid is given by:
volume=(length*width*height)/3
but in our case the base of the pyramid is square, therefore:
length=width=2 ft
height=6 ft
hence;
volume=(2*2*6)/3
volume=8 ft^3
The answer is 8 ft^3
There's a special case of the quadratic formula called the Shakespeare Quadratic Formula (2b or -2b) that applies when the linear coefficient is even.

If you're planning on solving a lot of quadratic equations quickly, it's good to know.
Here we have

Jacob had math homework on 81 evenings.
Step-by-step explanation:
Time spent of each evening = 1/3 of an hour
Time spent in minutes = 
Total time spent = 27 hours
Total time spent in minutes = 27*60 = 1620 minutes
Let,
x be the number of evenings spent doing math homework.
Time spent each day* Number of evenings = Total time spent

Dividing both sides by 20

Answer:
1764
Step-by-step explanation:
2% of 1800 = 0.02 * 1800 = 36
1800 - 36 = 1764
Answer: 1764
X = third angle
82° + 62° + x = 180°
144° + x = 180°
x = 36°
