Answer:
The height, of 0.87 cm, is finding dividing the volume by the multiplication of the length and the width.
Step-by-step explanation:
A cereal box is a rectangular prism.
A rectangular prism has 3 dimensions, length(l), width(w) and height(h).
It's volume is:
V = l*w*h
In this question:
[tex]l = 43, w = 12, V = 450[/tex]
So
[tex]V = l*w*h[/tex]
[tex]450 = 43*12*h[/tex]
[tex]h = \frac{450}{43*12}[/tex]
[tex]h = 0.87[/tex]
The height, of 0.87 cm, is finding dividing the volume by the multiplication of the length and the width.
