Answer:
7 cm
Step-by-step explanation:
The volume of a rectilinear shape is the product of its length, width, and height. Fill in the given information and solve for the width.
... V = l·w·h
... 1344 cm³ = (3·8 cm)·w·(8 cm) . . . . . . to find w, divide by its coefficient
... 1344 cm³/(192 cm²) = w = 7 cm
The width of the box is 7 cm.
