Answer:
Explanation:
Given:
Volume of square prism = 810 cubic inches
Height of square prism = 10 inches
The volume of a square prism has this formula:
v = a²h
a = side length of the square prism
h = height
810 in³ = a² * 10in
810 in³ ÷ 10 in = a²
81 in² = a²
√81 in² = √a²
9 in = a
The length of each side of the base is 9 inches. Only 5 sides of the cardboard box has a cardboard because the 6th side is open.
