Question
Making use of the cube root table, find the cube root $1100$
✓
Answer
We have: $1100 = 11 \times 100$
$\therefore\sqrt[3]{1100}$
$=\sqrt[3]{11\times100}$
$=\sqrt[3]{11}\times\sqrt[3]{100}$ By the cube root table,
we have: $=\sqrt[3]{11}=2.224$ and $\sqrt[3]{100}=4.642$
$\therefore\sqrt[3]{1100}$
$=\sqrt[3]{11}\times\sqrt[3]{100}$
$=2.224\times4.642$
$=10.323$ (Up to three decimal places)
Thus, the answer is $10.323.$
