What is the surface area of a cube that has a side length of 8 mm?

Use the formula is S A = 6 s squared, where SA is the surface area of the cube and s is the length of each side.
48 Millimeters squared
96 Millimeters squared
384 Millimeters squared
2,304 Millimeters squared

answer

SA = 384

set up equation

the given equation to use is

SA =

where s is the side length

values

s = 8mm

plug in values and solve

SA =

SA =

SA = 6 * 64

SA = 384

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
