The volume of a plastic storage
cube is 27,000 cubic centimeters. What is the
edge length of the storage cube?

volume= length times breadth times height

therefore cube root 27000cm3 (opp of cube is cube root) = 30 cm

so therefore answer is 30 cm for length 

all sides of cube is same 

check 

30 times 30 times 30 

27000

the answer is b.

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
