Question 4 of 10 ABC Bookstore uses a storage unit that measures 14 ft x 15 ft x 14 ft. What is
the volume of this storage unit?
A. 2100 cubic feet
B. 2100 cubic inches
C. 2940 cubic feet
D. 2940 cubic inches

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
