1. if length of one side of cube is 20 cm, then volume of cube must be:

a. 4000 cm^3
b. 8000 cm^3
c. 800 cm^3
d. 6000 cm^3

2. the volume of a cube is 64 cm^3 . what is the length of one side?

a. 6 cm
b. 8 cm
c. none of these.
d. 2 cm

2. c. None of these

1. b. 8000 cm.³

Step-by-step explanation:

2.

Unfortunately, we do not have an answer choice of , so we leave it as "None of these".

* All edges\sides of a square\square prism [cube] are congruent, so you take the cube root of 64 to get the length of each edge.

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.

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
