Answer:
0.84 m
The side of the cube with the surface area of 240 square meters is <u>0.84 meters</u> longer than the cube with the surface area of 180 square meters.
Step-by-step explanation:
The correct question must be:
The formula gives the length of the side, s, of a cube with the surface area, SA. How much longer is the side of the cube with a surface area of 240 square meters than a cube with the surface area of 180 square meters ?
Given formula to calculate side of a cube:
where is the side of the cube and is the surface area of the cube.
For a cube with surface area of 240 square meters, the side can be calculated as:
For a cube with surface area of 180 square meters, the side can be calculated as:
<em>The difference in the sides of the cubes is</em> =
Thus, the side of the cube with the surface area of 240 square meters is 0.84 meters longer than the cube with the surface area of 180 square meters.
