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

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
