Question

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

Answer 1

2. c. None of these

1. b. 8000 cm.³

Explanation:

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

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

1.
`whl = V \\ \\ 8000 = {20}^(3)`

* 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.

Answer 2

1 b

2 c

Explanation:

1) 20*20=400

400*20=8000

2)4*4*4=64
