Question

Find the cube of following decimal numbers:
(a) $0.7$
(b) $0.09$
(c) $1.1$

Answer 1

We have,

$\left(a\right)0.7$

$(0.7{)}^3=0.7\times 0.7\times 0.7=0.343$

$\left(b\right)0.09$

$(0.09{)}^3=0.09\times 0.09\times 0.09=0.000729$

$\left(c\right)1.1$

$(1.1{)}^3=1.1\times 1.1\times 1.1=1.331$

Hence, this is the answer.
