Question

find the length of a side of a cube if volume of the cube (cubic unit). is 1000+30x(10+x)+ x³​

Answer 1

Answer:

$x + 10$

Step-by-step explanation:

Volume : $1000 + 300x + 30x^2 + x^3$

from the volume of a cube, we can get the length of the side by using

cube root

firstly, check that

$1000 + 300x + 30x^2 + x^3 = (10 + x)^3$

so we can get the side length of a cube is

$\sqrt[3]{(x + 10)^3} = x + 10$
