Question

A) Find the volume of a cube whose edge is 'a' units B) Find the edge of a cube whose volume is 1000cmcube

Answer 1

b) volume of cube = a^3

1000 = a^3

cube√1000 = a

10 = a

a) volume of cube = a^3

please follow me

Answer 2

Answer:

A)

$volume = {edge}^{3} \\ = )( {a)}^{3} \\ = ) {a}^{3}$

B)

$volume = {edge}^{3} \\ = ) {edge}^{ 3} = 1000 \\ = )edge = \sqrt[3]{1000} \\ = )10 \\ hence \: edge \: is \: 10cm$

Hope it helped
