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

Respuesta :

Answer:

1 b

2 c

Step-by-step explanation:

1) 20*20=400

400*20=8000

2)4*4*4=64

Answer:

2. c. None of these

1. b. 8000 cm.³

Step-by-step explanation:

2. [tex]whl = V \\ \\ whl = 64 \\ \\ \sqrt[3]{64} = 4[/tex]

Unfortunately, we do not have an answer choice of [tex]4 cm.[/tex], so we leave it as "None of these".

1. [tex]whl = V \\ \\ 8000 = {20}^{3}[/tex]

* 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.
