Ответ:
Volume = Length * Breadth * Height
Volume of box = 450 cubic inches
Height of box = 2 inches
Length of box = x
Since it is a square prism, Breadth = Length = x
Therefore,
Volume = Length * Breadth * Height
⇒ 450 = 2 * x * x
⇒ 450 = 2x²
⇒ 2x² = 450
Divide the equation by 2
2x²/2 = 450/2
x² = 225
⇒√x² = √225
x = 15
The side length of the box is 15 inches
