What is the length of the side of a cube whose volume is 275 cm 3 . Make use of the table for the cube root.

Question

Philoid · Accepted Answer

Volume of cube = 275 cm³ (Given)

Let side of cube = a cm

So,

=

We know that value of

From cube root table we get,

=

So by unitary method,

∵ For difference (280 – 270 = 10 ) difference in cube root values = 6.542 – 6.463 = 0.079

∴ For difference (275 – 270 = 5) difference in cube root values =

Hence,

Thus the required cube root is = 6.503.
