Answer:

$307,572\ ft^{3}$

Step-by-step explanation:

we know that

The volume of a pyramid is equal to

$V=\frac{1}{3}Bh$

where

B is the area of the base of the pyramid

h is the height of the pyramid

Find the area of the base B

$B=114^{2}=12,996\ ft^{2}$

we have

$h=71\ ft$

substitute the values

$V=\frac{1}{3}(12,996)(71)=307,572\ ft^{3}$

Answer:

Step-by-step explanation:

Using PEMDAS you start with multiplication first, so -2 multiplied by -6, which is positive 12. Then you go from left to right, so 4 +-3, or 4-3, which is 1. Then 1-12 is -11. So your final answer is A, -11.
