Question

Which is the side length of a cube with a volume of 64 m3?

B.
`√(64) m`


C. 64 2m


D.
`\sqrt[3]{64} m`

the things that say "tex" are symbols after you click the question you will see the symbols. TIA:)

Answer 1

Volume = side x side x side

64 = side^3

Cuberoot both sides


`\sqrt[3]{64} = \sqrt[3]{side^3}\\\\\sqrt[3]{64} = side`


side = 4

side x side x side = 4 x 4 x 4 = 64 = volume

Your answer is D.
