The cereal box has a volume of 432 in if the base has dimensions of 2 in by 12 in what is the height of the box
OlgaM077 [116]

Answer:

Height of the cereal box = 18 in.

Step-by-step explanation:

A cereal box is in the shape of a cuboid.

And volume of a cuboid is represented by the expression,

Volume = Length × Width × Height

It's  given that volume of the box = 432 in³

Length of the base = 2 in.

Width of the base = 12 in

By substituting these values in the expression,

432 = 2 × 12 × h

h = \frac{432}{24}

h = 18 in.

Therefore, height of the cereal box is 18 in.

Find x for each of these triangles please
notka56 [123]

Answer:

8) 10°

9) X can not be determined.

10) 10°

11) 12 units.

Step-by-step explanation:

8) The three sides of the given triangle are equal. Hence, the triangle is an equilateral triangle, hence each angle will be 60°.

So, 6x = 60°  

⇒ x = 10°.

9) The three angles of the given triangle are equal. Hence, the triangle is an equilateral triangle, hence each side will be equal.

So, 6x - 5 = 6x

So, x can not be determined from this equation.

10) Δ KLM is equilateral, so, KN will bisect ∠ MKL. So, ∠ NKL = 30°

Hence, 3x = 30°

⇒ x = 10°

11) In Δ XYZ, XZ = XY , so, ∠ Z = ∠ Y.

Again, ∠ X is given to be 60°.

Therefore, each angle is 60°.

So, the triangle XYZ is equilateral, and each side will be equal.

So, 3x + 8 = 4x - 4

⇒ x = 12 units. (Answer)
