<span>A cube is a geometric three-dimensional solid object. It constitutes
6 square faces, sides and three meeting at each vertex. It is the only regular
hexahedron. A cube has a fixed number of
perpendicular angles. Typically, it has 8 perpendicular angles and each spigolo
or corner has 3 angles. Since it has 8 perpendicular (⊥) angles and 3 angles in
each corner, it makes up 24 angles.
All 8 ⊥ angles and 3 angles in each corner mean: 8*3=24.
Therefore, a cube has 24 right angles.</span>
Answer:
the amount of matter is mass. how much space you take up
Step-by-step explanation:
Answer:
123.948 km²
Step-by-step explanation:
We can use the equation: <em>AΔ = 1/2*ab*sinθ</em>, where a and b are the lengths of the sides next to the known angle, and θ is the angle itself.
Plugging in the numbers we know, we get: <em>AΔ = 1/2*22*24*sin(28°)</em>
Simplify: <em>AΔ = 264*.4695</em> (0.4695 is approximately sin(28°))
Simplify: 123.948 km²
Answer:
49 students
Explanation:
Since 70% of the 70 students passed the test, we can multiply 0.70 by 70 to get the number of students who passed the test. The word “of” is a hint that you should multiply.
0.70 * 70 = 49
>
Positive integers are always greater.
