<p>A<a>cube</a><a>number</a>is a value obtained by raising a number to the<a>power</a>of 3, or by multiplying the number by itself three times. When you cube a positive number, the result is always positive. When you cube a<a>negative number</a>, the result is always negative. This is because multiplying a negative number by itself three times results in a negative number.</p>

<p>Next, we must find the cube root of 3.5.</p>
46
<p>We know that the cube root of a number ‘x’, such that ∛x = y, where ‘x’ is the given number, and y is the cube root value of the number.</p>
45
<p>We know that the cube root of a number ‘x’, such that ∛x = y, where ‘x’ is the given number, and y is the cube root value of the number.</p>
47
<p>So, we get ∛3.5 ≈ 1.518</p>
46
<p>So, we get ∛3.5 ≈ 1.518</p>
