Question

Which equation finds the volume of a cube with a side length of 2 n Superscript 6 units?
(2 n Superscript 6 Baseline) cubed = 8 n Superscript 18 cubic units
(2 n Superscript 6 Baseline) cubed = 2 n Superscript 18 cubic units
2 (n Superscript 6 Baseline) cubed = 2 n Superscript 18 cubic units
2 (n Superscript 6 Baseline) cubed = 6 n Superscript 18 cubic units

Answer 1

Volume = side^3. With side = 2n^6:

(2n^6)^3 = 2^3 (n^6)^3 = 8 n^(6·3) = 8 n^18 cubic units.

So the correct equation is: (2 n^6)^3 = 8 n^18 cubic units.
