Question

the volume of A cube is 422 cm3 work out the length of a side rounded to 1 decimal place

Answer 1

Answer:

The length of a side rounded to 1 decimal place is = 7.5 cm

Step-by-step explanation:

The volume of a cube is 422 $cm^{3}$ = $r^{3}$ , where r= length of a side.

r= $\sqrt[3]{422}$ = 7.5 cm

Answer 2

As per the data given in the question,

We have to determine the value of length of the cube rounded off to 1 decimal places.

As per question,

it is given that,

Volume of cube $=422\:cm^3$

As we know that,

Volume of cube will be $=a^3$

Where, a = edge or side of cube.

So, we can rewrite the above formula as,

$a = volume^{\frac{1}{3}$

So, putting the value,

We will get edge as,

$a = 422^{\frac{1}{3}}\\a \approx 7.5\:cm$

Hence, value of edge of cube will be 7.5 cm.
