Please help meeeee.
A cube has the surface area 384cm2. What is the length of the cube?
HELP MEEEEEEEEEEEEEEEE
The cube has six faces, right? So each face must be what in square cm? Then each side of the square must be what?
6s2= 384
S2=384/6
S2=64
S=8cm
I'm here to help! Don't worry, we can solve this problem step by step.
To find the length of the cube, we need to know the formula for calculating the surface area of a cube. The formula for the surface area of a cube is given by:
Surface Area = 6 * (side length)^2
We are given that the surface area is 384 cm². By substituting this value into the formula, we get:
384 cm² = 6 * (side length)^2
Now, let's solve for the side length of the cube.
Divide both sides of the equation by 6:
384 cm² / 6 = (side length)^2
Simplify the left side of the equation:
64 cm² = (side length)^2
To find the side length, we'll take the square root of both sides of the equation:
√(64 cm²) = √((side length)^2)
Simplify:
8 cm = side length
Therefore, the length of the cube is 8 cm.
I hope this explanation helps you understand how to find the length of a cube given its surface area. Let me know if you have any other questions!
