Answer:
1000 cm^3
Step-by-step explanation:
First, Find the side length of the cube. The surface area is all the area on the surface of a 3-dimensional object. Since a square has 6 congruent faces the formula for surface area is 6s^2 where s is the side length. Since we know the surface area we can solve for the side length.
600=6s^2- DIvide by 6
100=s^2- Take the square root of both sides.
10=s
The volume of a cube is s^3.
10^3=V
1000=V
It would be 315151515/1000000000
count the digits after decimal, divide that by the power of tenth of that
Answer:
7.9
