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.
