Question

If length of one side of cube is 20 cm, then volume of cube must be...

A: 4000 cm 3

B: 6000 cm 3

C: 800 cm 3

D: 8000 cm 3

Answer 1

D

the volume (V ) of a cube = s³ ( where s is the length of the side )

here s = 20, hence

V = 20³ = 8000 cm³

Answer 2

Volume = l*w*h
All sides of a cube are congruent

20*20*20=8000

Answer: d) 8000 cm^3

Hope this helps :)
